In the scene where Dean is testing the joy buzzer on the ham, he raises the shield on his safety glasses in shock when he turns to speak to Sam, but in the next cut when Dean goes to take them off his head the shield is back down again.
Jesse: She said I was half demon. Is that true?
Sam: Yes, but you're half human, too. You can do the right thing. You've got choices, Jesse, but if you make the wrong ones, it'll haunt you for the rest of your life.
Jesse: Why are you telling me this?
Sam: Because I have to believe someone can make the right choice. Even if I couldn't.
Sam: Dude, what the hell?
Dean: I had a hunch I went with it.
Sam: You risked my ass on a hunch?
Dean: You're fine. Besides now we know who's turning this town into Willy Wonka's worst nightmare.
Sam: The kid.
Dean: Yeah, everything Jesse believes comes true. He thinks the Tooth Fairy looks like Belushi, uh, joy buzzers really shock people, boom that's what happens.
Sam: Yeah, but convince him that joy buzzers don't actually work and they go from killer machines back into crap toys.
Dean: Probably doesn't even know he's doing it. How is he doing it?
Sam: (seeing Dean's magically hairy palms) Oh, d-dude... that's not what I think it is, is it?
Dean: I got bored. That nurse was hot.
Sam: You know you can go blind from that, too.
Jesse: What, didn't your dad tell you about the Tooth Fairy?
Dean: My dad? My dad told me different stories.
Castiel: (sits on a whoopee cushion) That wasn't me.
Dean: Who put that there?
Sam: So we tell him the truth.You say Jesse's destined to go dark side--fine. But he hasn't yet. So if we lay it all out for him... what he is, the Apocalypse, everything--he might make the right choice.
Castiel: You didn't. And I can't take that chance.

Injoke: The nurse that Dean hits on is named Fremont, a nod of the head to Anthony Fremont, the little boy with a similar power to alter reality with a thought, seen in the original Twilight Zone episode "It's a Good Life". The same injoke was used in season 3's "No Rest for the Wicked".
Sam: Hit it, Mr. Wizard.
Referencing Don Herbert, who rose to fame as Mr. Wizard, the creator and host of four science-based educational TV series. He first appeared on the air in 1951 and after the initial show was canceled after 547 episodes, went on to produce three similarly-themed television programs.
Dean: That'll do, pig.
Referencing the novel The Sheep-Pig by Dick King-Smith, subsequently made into a popular movie, Babe, in 1995 with the screenplay by George Miller. Babe is a piglet adopted by Farmer Hoggett. Through a series of events, Hoggett discover that Babe can do anything that a sheep dog can. Hoggett says "That'll do, pig" in praise of Babe when he succeeds in a final contest.
Dean: Cavity creeps get ahold of him?
Referencing commercials for Crest toothpaste, which featured huge "Cavity Creeps" attacking the city of Toothopolis and chanting "We make holes in teeth!" Inevitably goodness and fluoride prevail as the cleaning power of Crest toothpaste drives them away.
Dean: Now I know who's turning this town into Willy Wonka's worst nightmare.
Referencing the 1964 novel Charlie and the Chocolate Factory written by Roald Dahl. It is better known because of the two movie adaptations, the 1971 movie Willy Wonka & The Chocolate Factory, or its 2005 remake Charlie and the Chocolate Factory. In all of them, Willy Wonka is the enigmatic yet often childish owner of a candy factory who invites children in with the hope of finding a successor.
Jesse: Like the X-Men?
Referencing the superhero team of homo superior created by Stan Lee and Jack Kirby in 1963. The members are born with an "x-gene" that typically gives them superhuman abilities. Professor Xavier, their initial leader and mentor, is a wheelchair-bound telepath (explaining Dean's comment about having someone in a wheelchair). They have been spun off into several animated series, and a movie franchise.
Dean: Agents Page and Plant, FBI.
Referencing guitarist Jimmy Page and vocalist Robert Plant of the famous rock band Led Zeppelin.
Referencing the lyrics from Greatest Love of All (Michael Masser, Linda Creed, 1977), best known as a top 100 song when covered by Whitney Houston in 1986 as part of her album Whitney Houston.
