I watch a lot stand-up comedy. I enjoy stand-up comedy more when I am at the club than watching it on TV. I guess it's more enjoyable when you have a whole crowd to laugh with. Here are some funny white comedians who you may never hear of:
Mitch Fatel (easily the funniest comic ever & has a Comedy Central special)
Tom Cotter (has Comedy Central special)
Brian Kiley (has Comedy Central special)
Darren Carter
Brendan Walsh
Claude Stuart
Greg Warren
Oh, and Ron White. I can't really stand the rest of those Blue Collar Comedy Tour guys, but Ron White is fucking hilarious. And sorry, I did not find Louis C.K. funny. From what I remember from his routine, all he did was bitch about how unhappy he is in his marriage. If you hate your wife so much, leave the bitch.
