First of all, anyone who names a female as a top contender for comedian has got mental problems. Women aren't funny. And most, if not all, female comedians are ugly as fuck. I just can't watch them... Paula Poundstone, Rosanne Barr, Ellen DeGeneres, Shelley Berman, Lily Tomlin, Rosie O'Donnell??? Are you freaking kidding me?
The closest to being funny (well, maybe humorous) was Tomlin when she was good, but I can't even watch Barr and DeGeneres and O'Donnell cuz they're too fucking UGLY !!! And not funny.
Now, to the real comedians...
I don't think I ever laughed harder that watching the first half of Eddie Murphy in Delirious. Geezus that was funny. Murphy has got to be one of the naturally funniest guys out there...all his stuff on Saturday Night Live was fucking brilliant, and on and on. But like most comedians, as time went on they got too commercial and became just stupid. Wasn't he in like Doctor Doolittle and shit? Just shameful for such a talented guy.
Kinda like George Carlin. In his day he was one of the best. But then he became an angry old man and I couldn't even watch him.
Bill Cosby was also on the top when it comes to stand up. Until he just relied on being able to 'wing it' in every freakin' monologue, and sometimes it was just boring as shit. But the guy was a master.
And of course Pryor was one of the best, if not THE best. Absolutely brillant. Funny as FUCK. I felt so bad for the guy after he burned himself, and he just looked like a frail old guy who had lost his edge.
And I can't believe nobody mentioned Steve Martin, who, in his day, was an awesome standup comedian. Well, for a short while he was. He was one of my favorites, and his Saturday Night Live stuff was incredible. Though now that I look back on recordings of some of that stuff he doesn't seem as awesome as I remember at the time, but anyways....
But there were a lot of guys who were just great to watch in movies and shit, but weren't necessarily that FUNNY in a standup sense. John Candy was a great character guy who was fun to watch, Belushi was great, Mike Myers was awesome to watch in sketches and movies (I loved all that Austin Powers stuff, except where they did disgusting poop jokes), Jim Carey is an incredible comic actor. Chevy Chase was very watchable, but he relied on prat falls way too much.
On the other hand, guys like Robin Williams were just annoying to watch. His standup was just this insane stream of consciousness nonsense that really wasn't funny, but he figured if he said it all fast enough then if he bombed with one joke there was another coming along in 2.5 seconds. Seinfeld just wasn't funny, but his show was one of the best on TV in spite of him being involved. Steven Wright wasn't funny, just annoying. Neither was Carrot Top...no different from that useless Sledge-A-Matic guy who just pulled out stupid props.
Now I was also a big fan of Jonathan Winters way back when. Funny guy doing standup, and great in movies. But he was a little too improv and stream of consciousness for me.
