Xander: I’m not gonna say it.
Willow: You lied to Giles.
Xander: ‘Cause she will.
Buffy: Look, I wasn’t lying. I was just… protecting him from information that he wouldn’t be able to… digest properly.
Xander: Like a corn dog.
Willow: Like you don’t have a sick mother, but you’d rather go to a frat party where there’s gonna be drinking and older guys and probably an orgy.
Xander: Whoa! Whoa-ho-ho, rewind. Since when do they have orgies, and why aren’t I on the mailing list?
