Dovid Sondik alleges the clip, entitled Flying Rabbi, which shows him ranting in Yiddish, was played on Jimmy Kimmel Live in August (10).
He says he was never asked before TV bosses used the recording and he filed suit in Brooklyn Supreme Court on Monday (13Dec10).
Sondik accuses Kimmel of appropriation of likeness and violating YouTube's service terms, and claims the clip has ruined his reputation.
He tells the New York Post, "It has caused me difficulty and pain. Now they think I'm a joke, a comedian."
Sondik is seeking unspecified damages.
