"What the Butler Saw" is a play written by Joe Orton, and David Tennant played a character in it. The play is a sexual farce, and Davids character spends a scene completely naked. In 1995, David Tennant appeared in a production of "What the Butler Saw". There is a Reddit thread where someone mentions that they think of a different image when they think of David Tennant in that particular play, involving a police hat being worn (and nothing else) . There is also a Pinterest post with a picture of David Tennant dressed in drag as Kiki Dee in a new TV show, but it is not related to "What the Butler Saw".
