I've mentioned this before (a couple of times I think)- THE funniest scene ever is not performed by Columbo himself, but a murderer. In "Columbo Goes to College" one of the killers does a dead-on impersonation of Columbo ("You know what I gotta do - I gotta go see the coach's wife!!") ANY Columbo fan will smile ear-to-ear no matter how many times you've seen it.
