The Sock and Buskin are two ancient symbols of comedy and tragedy. In Greek theatre, actors in tragic roles wore a boot called a buskin that elevated them above the other actors. The actors with comedic roles only wore a thin soled shoe called a sock.

In "Brian's Play", Buskin notes at the premier of Brian's play A Passing Fancy at the Quahog Playhouse that as usual, the play would suck for one of them.

Buskin is voiced by Danny Smith.
