Comedy writer Spike Feresten has written for some of the most influential shows of the ‘80s and ‘90s: 'SNL,' 'The Simpsons,' and 'Seinfeld.' His latest writing project was another collaboration with Jerry Seinfeld — the screenplay for the 2024 film 'Unfrosted.' For his treat, he cites a late night maverick who showed him that a career in the kind of comedy he loved might be possible.
