Okay I'm going to be "that guy". Not one of you has mentioned George Burns, who smoked cigars onstage, and both Dice Clay and Ron White would be on their freaking KNEES at that dude's feet when it comes to stand-up comedy. No one compares to the old school classics, no one. Give me Rodney Dangerfield over any of these guys in a split second. Eddie Murphy and Chris Rock combined couldn't even come close to Richard Pryor, let alone Flip Wilson, let alone Redd Foxx. My wife and I went to see Chris Rock a few years back live, and I swear I laughed once.
Ron White is funny if you're stuck with what's left of stand-up comedians in the new era, but I'd rather watch Buddy Hackett or Bob Hope or George Freakin Carlin tear it up on some 30-year old video footage than Ron White and his frosted tips and $2500 facelift. There was an episode of Letterman back in the 80s when Robin Williams (then very young) and Jonathan Winters (who really isn't even stand-up) and they did some spontaneous improv that basically blew away anything any of the new generation could do even with all their focus groups and stuff. I defy anyone side by side to look at Dangerfield in his prime versus the whole Blue Collar Tour, it's not even close. Three, four guys and Dangerfield would have left them in a scrap heap in 5 minutes.
Stand up comedy is dead.
