(Lilith tells Sam she found Rebecca in bed with Frasier; this is news to Sam & the gang)
Sam: We were just over there. We were watching "Three Stooges" tapes with him.
Norm: Maybe she was upstairs the whole time and we didn't know about her.
Cliff: Well, uh, after we left, maybe he, uh, just toddled on upstairs and gave her the old "nyuk, nyuk, nyuk."
