Question: I recently saw an episode of John Favreau's Dinner for Five in which George Carlin mentioned that he appeared on The Tonight Show 135 times during Johnny Carson's years as host (he had other appearances in the pre-Carson years), but that he did not hold the record for the most appearances on the show. This really got me wondering. Can you tell me who does hold the record? Thanks! — Bryan S., Austin, Tex.

Televisionary: As near as I can figure, Bryan, that would be David Brenner. The veteran comic has showed up on Tonight 158 times.
