His notoriety resting with near exclusivity on the strength of one character, Bob Einstein was better known for playing the wholly fictional and thoroughly inept stuntman Super Dave Osborne than he was for being the brother of comedian-filmmaker Albert Brooks. The son of a radio comic, Einstein was working in advertising and dabbling in comedy when he was handpicked by Tommy Smothers to join the staff of "The Smothers Brothers Comedy Hour" (CBS, 1967-69) alongside fledgling gag men Steve Martin and Rob Reiner. With the series' controversial cancellation in 1969, Einstein found himself a writer in-demand and created the character of Super Dave for the syndicated "The John Byner Comedy Hour" (1972). Perfecting the bit on the Canadian sketch comedy series "Bizarre" (CTV, 1980-85), Einstein later hosted his own variety show and voiced an animated series. A popular talk show guest and "Hollywood Squares" (1998-2004) panelist, Einstein starred in MGM's Super Dave feature film in 2000. Turning in later years to character work, he made memorable appearances on the critically lauded Fox sitcom "Arrested Development" (2003-06) and on HBO's award-winning "Curb Your Enthusiasm" (2000- ), on which he recurred as bullying retiree Marty Funkhauser. On the cusp of turning 70, Einstein donned Super Dave's star-spangled jump suit one more time for a four-part SpikeTV special in 2009, proving that neither advanced age nor the vagaries of the American comedy scene could keep a funnyman down.
