"What the Butler Saw" is a play written by Joe Orton, and David Tennant played the character of Nicholas Beckett in the 1995 Royal National Theatre production. The play is a sexual farce, and Davids character spends a scene completely naked. According to a Reddit post, David Tennant wore a police hat (and nothing else) in a particular image from the play. A photo of David Tennant in the play was shared on Twitter by David-Tennant.com in 2015. There are also several images of David Tennant in "What The Butler Saw" on Pinterest.
