This is the only Series that did not end with a Compilation episode.
This is the last ever episode of Whose Line? to be set in the UK.
Ryan starts to read the credits before Clive even says, "Good night!"
Notice how American Brad didn't know what the British show Eastenders was, but British Steve picked up right away on the American show Starsky & Hutch? Clive noticed that too, just before Colin came in he said 'Long memory you've got.'
Colin only has one line in Questions Only, which he says in French. It is: Avez-vous une cigarette? (Do you have a cigarette?)
