[flashback:]
Young Sherry: How much do we have?
Young Monk: [shakes tin] $18.25.
Sherry Judd: How do you do that?
Young Monk: I don't know. [chuckles] It's kind of funny, raising money for a dance that neither of us is going to. Uh, Leo, here's the thing, you gotta pay for that.
Leo: [wolfs down cupcake] Pay for what? Where's your evidence, Columbo?
Young Sherry: Leo, I'm telling principal Thicket. I'm not kidding.
Leo: You don't wanna do that, Sherry. You'll be sorry. I mean it.
Young Monk: Are you gonna pay us or not? [Leo squirts chocolate sauce on Monk's shirt]
Young Sherry: Leo, I'm telling. I'm serious! Here, it's okay. It's only chocolate. Here. [hands Monk a serviette]
Young Monk: Thanks.
Young Sherry: You should carry these with you.
