Started as a writer's-room voice on Sid Caesar's Your Show of Shows alongside Neil Simon and Carl Reiner, then spent the rest of his career turning parody into a career-length project: Get Smart, The Producers, Blazing Saddles, Young Frankenstein, Spaceballs. He is one of the small handful of people to win an EGOT, and took The Producers to Broadway in 2001, where it ran for six years and won twelve Tony Awards.
