I agree that they're not making TV comedy the same anymore, likewise radio comedy ( R/e Burns + Allen)or vaudeville. Times change but I agree that there is no reason to be vulgar. As far as really funny clean humor from the 60s + early 70s I give it to the Smothers Brothers + Carole Burnett with kudos to Tim Conway!
Used to enjoy that show, WKRP. The turkey drop episode was one of the best. That and the episode that they all end up going to see a "new" 3-D adult movie.
