 Paul Gross (I) (qv) plays Geoffrey Tennant, a stage actor best  known (before his mental breakdown) for his performance as Hamlet.  In an episode of _"Due South" (1994)_ (qv) titled "A Hawk and a  Handsaw", Gross character Benton pretends to be insane, not unlike  the character of Hamlet. The name of the episode comes from a line  in Hamlet where he tells Rosencrantz and Guildenstern that he can  "tell a hawk from a handsaw"
