Puck was a character in William Shakespeare's play A Midsummer Night's Dream. In the play, Puck was the court buffoon to Oberon.
When an away team from the USS Enterprise-D was trapped in 1893 San Francisco, the team members claimed to be actors having performed A Midsummer Night's Dream in Milan, London, and Paris. Lieutenant Commander Data played Puck. (TNG: "Time's Arrow")
