Frasier: Hey, Kelly. Have you ever seen eighty beavers march in perfect rhythm?
Kelly: Oh, Frasier, everyone knows beavers can't march.
Frasier: Oh, they can, when they're the marching beavers of the Riverside High School Band!
Kelly: Hey, you tricked me.
Frasier: Sorry, Kelly, but how about those incredible formations. They're so precise.
Kelly: Well, that doesn't surprise me, Fras, after all, the beaver is nature's first ENGINE-er! (laughs)
