Look Closely: When the guy in the pebble scam drops the extra coins into the bag (already holding 20 silver pieces) that Toph is going to get if she wins, he only drops about five pieces. But Toph just said she would do it for 40 pieces so he didn't drop nearly enough in the bag.
At the end of the first try, the card shark attempted to stash the pebbles in his sleeves but he did so by just scooping the bowls backwards, flinging the pebbles into his sleeves with no attempt to hide what he was doing.
When Katara prepares to bend at the beginning of the training session, the dark red stripe at the bottom of the red skirt is gone.
As Katara uses her own sweat to break out of jail, notice that for the last move, Katara gets her water from her armpits.
When Combustion Man captures Katara, his metal hand is golden. As he attacks Aang and Sokka, however, it is gray.
As was brought to our attention earlier on, there isn't really any way to direct where Hawky sends his message. Yet, at the end of the episode he seems perfectly capable of delivering Toph's letter to a part of the world he's never been to.
While Sokka and Toph talk about Katara, we can see that the cliff is very thick, too thick for their feet to pass it. But when Katara notices them from below, she can see their forelegs and feet.
When Combustion Man chased Aang and Sokka, in one scene we can see that they were running away from the back of the Ozai statue, but moment later when Aang ran using the same route, he hit the front of the statue, which was impossible.
In the scene where Toph and Katara were arguing over the issue of scamming, there was a white paper scroll beside Aang, at first the scroll was behind the monkey statue (which is on the statue's left in the perspective of Aang), just a moment later, the paper scroll switched position with the monkey statue.
When Toph was in town scamming and rolled the dice like sticks, it was impossible for her to see what was on the dice since she was blind, therefore couldn't earthbend the dice into the right pattern so that she could win.
When Toph ate her apple after scamming in town, we could see she already had one bite on her apple, but later, the bite disappeared before she took another bite.
While Katara is showing Toph the wanted sign that she found, she is barefoot, but later in the argument, when we see a birds-eye view, she is wearing sandals.
When Aang, Sokka, and Toph return with the supplies, all the supplies are being carried in Water Tribe baskets. Why on earth would they use those baskets while they were trying to blend in with the Fire Nation?
When Toph is captured and dragged away, the soles of her shoes have been replaced; they'd been punched out to help her "see" until then.
During the scams, when Toph was playing dead, Sokka was wearing the same beard that he wore in The Headband.
Katara gets mad at Toph for endangering the team and their mission for her personal interest, yet she did the exact same in "The Waterbending Scroll".
When Katara is arguing with Toph, she is barefoot. When the argument is over, she is seen stalking away in sandals.
Look closely when Katara sends the huge wave of water at Toph, the water makes a small arch around Aang, then closes back up right before it reaches Toph. (Most likely Katara made it do that so it would splash Toph, not Aang.)
Katara: Aang, do I act motherly?
Aang: (Aang rubs his eye and stutters) Um...I.
Katara: Stop rubbing your eye and speak clearly!
Aang: Yes Maam!
Toph: Why? Because it's fun? And you hate fun?
Katara: I don't hate fun! (picks Momo up and puts him on her head like a hat) See? Fun!
(Momo falls off, chatters angrily and runs away)
Toph: A wanted poster! That's so great! The Runaway... I love my new nickname! Is there a picture of me? Does it look good?
Sokka: (considers the picture for a second) Well, yeah, actually, it does look pretty good... but, Toph, you're missing the point!
Aang: It's Sparky Sparky Boom Man!
Sokka: You know, I'm starting to think that name doesn't quite fit!
Sokka: Hey, I've got it, the perfect name for that guy. "Combustion Man"!
Toph: Good job, Sokka. Now let's get out of here before Combustion Man catches us!
Sokka: See? It fits so well!
Katara: What's this? (unfurls a sheet of paper)
Toph: I don't know! I mean, seriously, what's with you people?! I'm blind!
Toph (to Katara): Could you for once stop being such a sour-puss and just lighten up? (flips Katara a coin)
(Toph tries to run away but get captured in a net)
Toph: How could you do this to me? You betrayed me!
Katara: You brought this on yourself. I had no choice.
(Fire Nation Guards take Toph away)
Toph: So let me guess. You brought me out here to tell me your sister is not as annoying as I make her out to be?
Sokka: Nah she's pretty much a pain. (pauses for a moment) She's always got to be right about everything and she gets all bossy and involved and in your business.
Toph: Yeah. I don't know how you can deal with it.
Sokka: Actually, in a way, I rely on it.
Toph: I don't understand.
Sokka: When our mom died, that was the hardest time in my life. Our family was a mess. But Katara, she had so much strength. She stepped up and took on so much responsibility. She helped fill the void that was left by our mom.
Toph: I guess I never thought about that.
Sokka: I'm gonna tell you something crazy. I never told anyone this before. But honestly, I'm not sure I can remember what my mother looked like. It really seems like my whole life, Katara was the one looking out for me. She's always been the one that's there. And now, when I try to remember my mom, Katara's is the only face I can picture.
Toph: The truth is, sometimes Katara does act motherly, but that's not always a bad thing. She's compassionate and kind and actually cares about me. (Toph wipes away her tears) You know, the real me. That's more than my own mom. (She punches Sokka on the shoulder.) Don't ever tell her I said any of this!
Sokka: Hey, my lips are sealed.
Katara: Hey, Toph. Um, I wanna--
Toph: Katara, stop. You don't need to apologize. I was the one being stupid. These scams are out of control, and I'm done with them.
Katara: Actually, I wasn't going to apologize! I was gonna say I wanna pull a scam with you!
(Sokka and Aang gasp)
Toph: What? You wanna pull a scam?
Katara: Not just any scam! The ultimate scam!
(Sokka and Aang faint)
Katara: Whaddaya say, Toph? Just me and you. One last go. You in?
Toph: You know I'm in! So what's this idea of yours?
(Sokka and Aang groan)
Katara: Sokka, please don't tell me you bought a bird.
Sokka: Not just any bird, a messenger hawk. Now we can send messages anywhere in the world, even to Gran Gran.
Aang: Sounds neat! How does it work?
Sokka: (thinks about it) You know, I never thought about it. (addresses messenger hawk) Hawky, Gran Gran! (Sokka points with his finger; Hawky looks at him and shakes it's body) I think he gets it.
(Sokka and Aang attempt using Hawky to forge an apology letter from Toph to Katara)
Katara: (shouting to Sokka and Aang after reading the forged letter) I know this is from you, Sokka! Toph can't write! Ugh! You're all driving me crazy!(rips letter up and storms away)
Aang: I can't believe we forgot Toph can't write...
Sokka: Yeah, we're idiots.
Aang: I guess Plan B is we send a note to Toph pretending it's from Katara.
Sokka: I think we're going to run into a similar problem.
(During Aang's training session, Sokka charges up from behind)
Sokka: Aah! Sneak Attack!! (Gets hit with an earth wall)
Aang: Sokka, sneak attacks don't work if you yell it out loud.
(Katara begins working up a sweat while she and Toph are trapped in a wooden cell)
Toph: What are you doing?
Katara: I'm making my own water. (starts to slice the wooden bars apart by waterbending her sweat)
Toph: Katara, you're a genius! A sweaty, stinky genius!
Sokka: This guy is too good! He shoots fire from his brain!
Sokka: Cute little Hawky. Who's got pretty feathers?
(Katara and Toph are locked in a wooden cell so that neither can 'bend their way out)
Toph: Wait! It's a trap!
Katara: (sarcastically) Really? No kidding! Is that why we're sitting in a wooden cage right now? Gee, how'd you figure out it was a trap?
Toph: Not for us, Katara; we're the bait. He wants Aang.
Katara: I can't believe I was so stupid. See, this is exacly why I'm against these scams; I knew this would happen.
Toph: But this was your idea.
Katara: I know. I wanted to show you that I'm not so motherly. I wanted to show you that I can have fun too.
Toph: Katara, you are fun. If nothing else, you're at least fun to argue with.
Katara: I know your relationship with your parents is complicated, and I shouldn't of said what I said.
Toph: It's okay. I was really mad when you you said that because, well because maybe it's true. I try not to think about, but when I left, I probably really hurt them. (snivels a bit)
Sokka: Toph, when I was in town, I found something that you're not gonna like. (shows a Wanted Poster to her)
Toph: Well, it sounds like a sheet of paper, but I guess you're referring to what's on the sheet of paper.
Sokka: It's a wanted poster of you!
This episode is available in the Avatar Book 3: Fire Volume 2 DVD along with The Avatar and the Firelord, The Puppetmaster, Nightmares and Daydreams, and The Day of Black Sun Part 1: The Invasion.
Turbonick showed this episode before it aired.
This episode first aired in the UK on October 25, 2007, 8 days before its scheduled airing in the US.
In Celtic mythology, a hawk stands for recollection, cleansing/ clearing of guilt. This is especially relevant when Toph sends Hawky with a letter to her parents to settle matters with them.
Toph pretending to be hit by a carriage carrying a wealthy merchant is very similar to a real insurance scam called a Flopsy.
Sokka mentioning how he wouldn't have to talk to anyone with the use of a messenger hawk is possibly an allusion to the popular sentiment of today's text-messaging culture.
Toph says "Wait, it's a trap!" This seems to be a allusion to Admiral Ackbar from Star Wars: Episode VI quote. This quote has also spawned a internet meme of sorts.
Katara's big scam is very similar to the 1966 movie The Good, the Bad and the Ugly. The movie has a small plot of the main character Blondie traveling town to town to collect the bounty on a wanted man. Then later freeing the man, and splitting the reward.
The statue in the center of town in this episode is very similar to the Colossus of Rhodes.
