'Columbo' was mentioned in two shows this past week: 'Rescue Me' and 'Psych'.

Tommy Gavin (Denis Leary) said that if his life was a 'Columbo' episode, somebody's questioning of him would have had him soiling his pants by that point.

And on 'Psych', the main character Shawn referred to his partner Gus as "Chocolate Columbo" for figuring out where a missing teen was.
