Oh man I have so many but if I really had to narrow down my favorite favorite it's Jack Benny, far and away. The funniest person on the planet and I often joke that I'm like a trans girl version of Jack Benny. If I could even be 10% as funny as he was I'd honestly be set for life. For a good example of his kind of humor, this video is worth a look: https://www.youtube.com/watch?v=IeOtLAv82mA

My other favorites at the top of the list would be: Steve Allen, Bob Newhart, Groucho Marx, Ernie Kovacs, George Carlin, Mel Brooks, Jack Carter, Garry Shandling, Tom Dreeson, Garry Moore, Carol Burnett, LaWanda Page, Sam Levenson, Lucille Ball, Rodney Dangerfield, and I could keep going but I'll stop there. Love me some old people comedians.
