Cosby, nope, apparently. Tosh O., negative. Ditto Wierd Al.
The list of those bringing the funny is getting smaller and smaller, judgnig solely by SC thread titles. So tell me, who IS funny?
Tim Conway and Harvey Kormann
Chris Rock
Bill Engvall
Ron White
My cats on catnip.
Me.
My typing skills are laughable…
What isn’t funny? I laugh at things in the world all day long.
The only comedians I’ve found consistently funny and/or just really interesting to listen to are George Carlin and Mitch Hedberg. Unfortunately, they’re both fairly recently deceased. But their back catalog should keep you laughing and/or thinking for a while.
Chris Rock is brilliant. His last HBO special just made onto Comedy Central. See it.
He’s as good as anybody, and I go back to picking up George Carlin’s first album when it was new.
It’s worse than you think.
Few Hollywood actresses are actually attractive, a vanishingly small number of lead singers can hold a tune and most popular entertainments are poorly written / badly produced / fattening / irredeemably biased.
Fortunately, all SDMB members post endlessly imaginative, intelligent and intriguing comments. You’re welcome.
Frankie Boyle
Harvey Korman is dead. That’s not funny.
Louis CK.
Richard Jeni, RIP.
Jon Stewart, Stephen Colbert and the guys who do Futurama are consistently funny. Felicia Day’s “The Guild” is consistently funny. Rifftrax is consistently funny, though they aren’t ALWAY uproariously so, they care close enough. “The Soup” is hit or miss, but sometimes it REALLY hits. There are prolly other off and on funny people, but I cant recall them offhand.
No, most Dopers think that most Hollywood actresses are attractive in that “bland, Hollywood way”, with the exception of X and Y, who they would gladly leave their wives/go lesbian for.
Of course, when faced with the opportunity to hook up with that blandly attractive model/actress/singer, they would bonk her in a heartbeat.
He’s still funnier than Adam Sandler. 
You missed my point. Bill Cosby IS funny…or he WAS funny, until I realized after having kids that what he was telling us and what we were laughing at is TRUE.
Now it’s gone from knee slappingly funny to ‘yeah, my kids forget to turn on the water in the shower, too.’
Eddie Izzard.
Isn’t humor relative to your own perspective and social setting?
For a while, I dated the manager of The Comedy Club in Hermosa Beach. This is the place that the likes Jay Leno and Robin Williams would go to try out material so I saw a handful of incredibly successful comics working the crowd.
Note that I say successful. Because to me, they weren’t funny. Perhaps because I saw them developing their schtick that it all became rather contrived for me. I’m pretty much a downer when it comes to comedy clubs because I can’t remember ever laughing at one.
But then there is British black comedies. I love those. Rowan Atkinson and the whole Blackadder series makes me laugh. I like BritComs way more than American sit-coms. Fry and Laurie kills me.
Louis CK. He’s funny.
To me?
Currently: Louis CK, Paul F. Tompkins (check out his Pod F. Tompkast for free on iTunes), Greg Giraldo, Rob Huebel, Patton Oswalt, Chris Rock, It’s Always Sunny in Philadelphia.
Dead or past their prime: Andy Kaufman, Richard Pryor and Steve Martin at their peaks, Dave Chappelle (might make a comeback).
I don’t know if it’s possible to answer this. People think Larry the Cable Guy is funny - I think he’s juvenile. Others rave about Lisa Lampanelli - I think she’s tasteless. There are dozens of comics who get specials who I find to be crude or just plain boring. There are so few I find to be clever or amusing.
On my funny list are Groucho Marx, Mitch Hedberg, Tim Conway, Red Skelton, Jon Stewart, Gabriel Iglesias, and maybe a few more who don’t come to mind at the moment.
According to Benjy Stone in My Favorite Year, on the not funny side is “… anyone who has ever played the accordion professionally.”
