Wade tells Kim that the Kimmunicator battery needs to be replaced every three or four years, but her's only had about two years on it. She was given a new Kimmunicator in A Very Possible Christmas after her prior one was destroyed.
This episode is the first appearance of a new running gag for season four. It is that when Kim and Ron try to have a romantic moment, they are constantly interrupted by various people (usually being Wade).
When Ron tells Wade that he dressed like a girl before, he is referring to the time he and Kim switched bodies in the episode Mind Games.
In the order Disney is airing the episodes, Monique would not have acknowledged Wade without being surprised to see him since she has never seen him in person.
Ron: (to Wade, talking about Monique) So, I am going to teach you the fine art of charming and discarming.
Ron: Yes me! Excuse me, who's dating Kim Possible?
Wade: Yeah, but the laws of extreme improbability inexplicably worked out in your favor.
Señor Senior Senior: With the speakers on this apparatus, soon half of the world's population will be under our control.
Señor Senior Junior: And then I will be worshipped by millions! But my social calendar will be so full. Oh, I am tired only thinking on it!
(Senor Senior Junior is singing while being hugged by Kim)
Junior: (singing) You must pay the door...
Ron: Give me back my girlfriend!
(Ron takes off his wig and Junior laughs)
Ron: Dude, what is so funny?
Junior: Ha! Ha! Ha! I thought you were a lady!
Ron: Well, you are no gentleman.
Ron: Hey Wade, how's the new girlfriend?
Ron: But I thought you found out that she was a super genius like you.
Wade: Yeah, but she made her own cupid ray!
(After Wade leaves Monique to sit with another girl in the next booth)
Monique: Looks like everything worked out in the end after all (noticing she is alone) Oh great, I'm dateless yet again! (Notices Ned behind the counter winking at her) Dateless works!
Ron: (after Junior has stopped singing) Got any more hearing protection?
Wade: I wish...
Ron: (after seeing Wade get hit by a cupid ray) You don't think Kim has one of those?
Kim: Hey Ron
(Ron jumps and screams)
Kim: What are you doing?
Kim: You're weird.
Kim: Shh, (romantically) I like weird.
(Wade confronts Senor Senior Senor backstage at the club)
Senor Senior Senior: Your genius cannot beat my evil and treachery. Oh, by the way, have you met my bodyguards, Evil and Treachery?
(Ron sees Monique get affected by Wade's love ray)
Ron: Wade, you just did something with the bun warmer. (Holds up his hotdog) Can I borrow that?
(Kim and Ron arrive in Paris, France)
Kim: I thought you said the Eiffel Tower was in danger!
Ron: It is in danger, of rust, eventually!
(Wade reading Ron's note that he gave him to Monique)
Wade: The humble earthworm is vital to agriculture, it moves through the soil by excreting lubricating mucus.
Kim and Monique: Eww!
Ron: Wait! That's my biology report! Oh no! That means. . .
(camera cuts to Mr. Barkin grading Ron's "biology report")
Mr. Barkin: (sniffs) That's a beautiful thought. A-plus, Stoppable!
Wade: (with a beard and a large hat on) I look like Lincoln!
Ron: Ready for President's Day! (Looks at Rufus covered in hair) Oh, and Groundhog Day.
(Wade is talking to Kim about Monique via camera)
Kim: I saw how you were looking at Monique.
Wade: (Nervously) I-I wasn't looking at anything, I never saw her in person before, and she smelled so... (drifts off) nice, (comes back) oh, my mom is calling, got to go, situation, Earth's going to hit an asteroid, comet, something, president's calling. (makes a crackling noise and turns off the camera)
(Wade looks at Monique)
Wade: Mo, Mo, Mo
Ron: Uh, is this robo Wade?
Kim: You do know what happens in February, don't you Ron?
Ron: Groundhog Day? President's Day? Dental Health Month! Ooh, that reminds me, Rufus! (Rufus pulls out a toothbrush) Happy Dental Health month KP! It has a tongue scraper on the back.
Kim: (clears throat) Valentines Day?
Ron: Huh? Oh, I don't celebrate. I've never had a girlfriend on. . . (Looks at Kim, who is glaring at him) Holy canoli, I have a girlfriend on Valentine's Day!
Ron: Wow! This is huge!
(Ron is talking to Wade as they are sneaking into the all-girls club, dressed as girls)
Ron: I've done this before, but I was brain-switched with Kim.
(Ron giving Wade romance tips for Monique)
Wade: Shouldn't I just be myself?
Ron: No, that only works in cartoons!
Ron: So we hit a SNAFU. Thats okay, we'll try it again.
SNAFU is an army term originating around 1941 that means Situation Normal All F**ked Up. Much like similar psuedo swear words, this term has become acceptable in common conversation and simply means a badly confused or ridiculously muddled situation, or to be in disorder or out of control.
This is Spinal Tap:
In the TV spot for The Ear Splitters the announcer says they are "The loudest band on the planet." Being the "loudest band in the world" was Spinal Tap's claim to fame in the famous mockumentary.
Some Like it Hot:
The scene in which Ron and Wade have to dress up as girls to gain admittance to a ladies only concert is an homage to a similar plot from the classic 1959 teen movie, Some Like it Hot, with Marilyn Monroe, Tony Curtis, and Jack Lemmon.
Senor Senior Sr: Together, we will chase it around perdition's flame. . .
This was a famous line by Captain Ahab from the classic novel Moby Dick by Herman Melville. It was also used in a modified version in the famous movie Star Trek II: The Wrath of Khan, which starred Ricardo Montalban, the voice of Senor Senior Sr.
