Right after the opening song, there is a wide shot and you can see Bobby with a group of kids. On the furthest right, you can see Joseph. In the close up Joseph is not there.
In the scene at the school, Joseph's fork looks like it is sticking out of the table in the close up, but in the wide shot, when he goes to pick it up, it is on his tray.
In the scene when Bobby was doing dishes, Cotton is sitting at the end of the table, but in one shot it looks like he is on the side closest to the sink.
When Cotton first arrives at the party Bill is in the background without a shirt. When he jumps on the horse a few seconds later, he has a shirt on.
Bobby takes a bite of his brownie and leaves most of it on his tray when he starts to get up and the teacher comes over to talk about his attitude. A few seconds later, when he and Joseph start slamming their trays on the table, the brownie is gone.
When Hank is barbecuing and turns the steak over, there are four burgers on the grill. When he tells Bill that the steak is for his father, there are only three.
Didi says that they can leave now, but then leaves and goes and gets Cotton dinner before its official that they are staying.
When Cotton dumps food on Luanne's plate he puts some meat on it, plus she already had her own meat, however in the wide shot the only thing on her plate is corn pone.
In Cotton's flashback, we can see that Fatty was the one with the glasses because we see him getting eaten by the sharks. But when we see Cotton drag the other two onto the island, one of them looks just like Fatty.
In this episode, Cotton takes Bobby out of school because it's Angie Dickinson's birthday, which falls on September 30th. This means that Bobby's birthday may be September 29th as this scene takes place the next day, however it isn't specifically said that it was on his birthday. It could have been an early (or late) celebration.
At the party Bill is standing around the grill and he is wearing red shorts, but when he sits down to eat, he is wearing blue shorts for one shot then turns back to red.
Hank : Your mother's probably got a better head on her shoulders than anybody in Arlen.
Bobby : Better than Bill? Or Dale? Or Boomhauer?
Hank : Jeez Bobby. Why not compare her to a baboon in the zoo?
Hank : Now Son, pick up that phone and invite your granddad to your birthday party.
Bobby : Okay. (Picks up the phone and dials three numbers) Hi Grandpa.
Hank: Bobby, if you're gonna fake dial, you gotta hit more than three numbers.
Cotton (Telling Bill, Dale and Boomhaur the story about how he lost his shins): I was 14. Just a little older than Bobby. But I knew Uncle Sam needed me, so I lied and signed up. We had beat the Nazis in Italy and they shipped us to the pacific theater. A Tojo torpedo sent our troop ship to the bottom. I could only save three of my buddies Fatty, Stinky and Brooklyn. They were kind of like you fellas only one of them was from Brooklyn. Out of the sun came a Tojo zero. It put fifty bullets in my back. The blood attracted sharks. I had to give them Fatty. Then things took a turn for the worse. I made it to an island, but it was full of Tojos. They were spitting on the U.S. flag, so I rushed them. But it was a trap. They opened fired and blew my shins off. Last thing I remembered, I beat them all to death with a big piece of Fatty. I woke up in a field hospital and they were sewing my feet to my knees.
Bobby: (after talking to Connie) Woo, she's moody. Must be PBS.
Joseph: Everyone loves your party, Bobby.
Bill: (eating cake, all giddy) I'm having fun.
Dooley: Your wife divorced you.
(Bill's smile disappears as he puts down his cake fork.)
(Bill stands in front of a water slide)
Bill: This thing's a hoot!
(Bill dives down and slides across the water slide and crashes into a wooden fence)
Bill: Ah... I got a splinter.
Bobby: Miss, miss...
Cotton: You're not going to get no service that way! You gotta grab her in the moneymaker!
(slap waitress on the butt)
Cotton: Hey missy! How about some samiches?
Cotton: How do you like your mama's new ta-tas?
Hank: She is not my mother! Hell, we went to kindergarten together!
DeeDee: Hey Hank. Do you still like fingerpainting?
Bobby: Wow! A super squirter! Kahn: Super squirter! Cotton: This ain't no water toy, Khan! It's a 12-gauge shotgun used by the Alamo. Joseph: Wow, you got a real gun! Peggy: And now Peggy has a real gun. You're too young to own a firearm. Cotton: Did you see that, Hank? Tell your woman to give him his gun back. Peggy: His woman? I am my own woman!
Peggy: (after seeing Cotton shoot the pinata with Bobby's gun) You gave him a loaded shotgun!?
Cotton: You don't give a toy without batteries.
Dale: (to Cotton about Khan's race) He's Japanese.
Cotton: No he ain't. (Looks Kahn up and down) He's Laotian...ain't ya Mr. Kahn?
Bobby: (mimicking Cotton and slapping Peggy on the butt) Go on, woman, get me my dinner!
Bobby turns 12 in this episode. Not often a cartoon character ages (and he does it again in a later season too).
The writer of this episode was nominated for the 1997 Annie Award for Best Individual Achievement: Writing in a TV Production.
Cotton calls Peggy Hilary, most likely a reference to then First Lady, Hilary Clinton.
The title is an allusion to Sins of the father, a concept by which offspring are punished for the wrongdoings of a parent.
