Original SNL writer, partner with Al Franken, creator of Coneheads, notorious druggy, multiple Emmy Award winner, hilarious guy.
RIP. I heard an interview with him where he said he had a big falling out with Franken after Franken's first kid was born. Franken had decided to give up his partying ways when he became a father while Tom Davis kept on.
From what I've read, it only lasted about a year. Franken named a daughter after him: Thomasin Davis Franken.
