Frasier: Please, please don't throw us out.
Niles: We'll shut up, we promise.
Randy: You've promised that four times tonight. Sorry, you're gone.
Frasier: But what are we gonna tell our dad?
Niles: And my girlfriend?
Randy: Maybe you should have thought of that before you started goofing off.
Niles: Okay. So, uh, how's this work, Randy? You mail us our certificates of completion, or what?
Randy: Yeah. Um, let me go get a pen and paper for your addresses.
Frasier: All-righty.
[After Randy steps back into the classroom, Niles turns the handle on the door. It's locked.]
Niles: I'm starting to think he's not coming back.
