Interrogation was played once on the British series of Whose Line.
Interrogation is a variation of Courtroom Scene and Press Conference. Two performers are police officers interrogating a suspect for a crime. The suspect doesn't know what crime he commited, so he must work out what he did in the process of the game.
One of the more enjoyable one-time games, Interrogation featured one of the only times a contestant who wasn't playing the game had any lines during it, with Colin Mochrie piping in with a one-liner .
Ryan: And don't think that I don't see the guy behind the mirror!
Colin: I told you, you should've put the glass in the other way!
