Some good ones...
Worm guy: Ello.
Sarah: Did you just say Hello?
Worm guy: No, I said ello, but that's close enough.
Fozzie: Oh, I'm so nervous. If I'm not funny, I won't be able to live with myself.
Bunsen: Well, then you'll have to get another apartment, won't you?
Billy Bones: Aye, but also, beware running with scissors or any other pointy object! It's all good fun, until someone loses an eye!
Sam: Kermit, does this film have socially redeeming value?
Miss Piggy: That may be true, but I am a woman first.
Rowlf: No, you're not. You're a pig first. Nurse second. I don't think woman made the top 10.
Fozzie: A bear in his natural habitat. A Studebaker.
Kermit: That's pretty dangerous building a road in the middle of the street. I mean, if frogs couldn't hop, I'd be gone with the Schwinn.
