I wrote a clever post on the now deleted thread, but I won't ask to have it restored just so I can prove it... ;>)...but it referred to my wish to 'start over' in life and write about humor, as I agree with Peace that "The answer to the title of this thread has some very profound/deep implications."

Indeed, Red Skelton was one of the funniest men alive, because he could see variations on a theme and improvise on the spur of the moment (like my ex-wife and the fart) and keep you laughing long after most comics had exhausted their 'written' material.
