I like Joe Rogan's podcast, though I don't listen too often. I catch it every once in a while because I find he rehashes too many of the same topics with different guests, so listening too often isn't good. I don't find his stand-up very funny, nor is he particularly funny on his podcast.
Personally, I've never found the uber masculine dudes who work out all the time to be funny. Something about the profession, but comedy is one of the rare "celebrity" professions where I think being too good looking or concerned with body image is a detriment.
