This is Albert Brooks guesting on The Tonight Show on 2/24/1983. I linked to a shorter version of this about ten years ago but this is the complete segment which includes more jokes, including one for which Standards and Practices futzed up a few words they didn't want heard.

He was always fearless, going onto national TV shows with material he'd never tried-out in front of an audience. There was one night on The Tonight Show when Rob Reiner was guest-hosting and Brooks came on with a bit that absolutely died. But that was rare for him and this time, things couldn't have gone much better…
