I simply LOVE stand up comedy. Like mikelej14 I was always a Hedburg fan. Poor dude. Another deceased favorite was Richard Jeni. These guys were brilliant and it's a shame they left us so young. I suppose my enjoyment comes more from witty comedy rather than anything outrageous, slapstick or plain ignorant. Then again, I love watching Trailer Park Boys, Family Guy, old Beavis and Butthead, so who am I kidding?
Others I like a lot are -
Bryan Regan (never a swear word and will have you rolling!)
Maria Bamford (once you get her, she's fantastic)
The late George Carlin - legend!
Kevin "Bloody" Wilson - Aussie comedian with truly perfect delivery.
That's just to name a few. There are tons who are really good that don't get a lot of mainstream attention. Take the Blue Collar Comedy Tour guys. I don't find them funny at all really, more amusing. And Bill Engvall, not even that.
