This clip didn't go viral, but it's still just as funny.
I really wanted to find the episode where he's a guest on Norm Macdonald's podcast, but that seems to have vanished from the internet (ie youtube). Instead, here's a compilation of random clips with him and Norm from various different shows.
And just in case there's any doubts if Super Dave qualifies as "retro", BAM: Vintage spot on Johnny Carson.
He even had his own cartoon show!
Rest in Peace, you funny, funny, man. PS: Did you know that he was Albert Brooks' brother?
