Apparently it needs to be pointed out that the non-famous comedians on TV are not the funniest non-famous comedians out there.
Just because you've seen some boring white dude on a Comedy Central hodgepodge "special" doesn't mean he's supposed to be funny. Those people that get on TV are there because their schtick lends itself to television better than live. They look normal...they are hygeinicly well-kempt, they don't lean on a lot of racial jokes or sex jokes in their act, etc.

There are all kinds of boring white dudes and women on Comedy Central. Don't judge white comedians by this! I go to clubs all the time and there are hilarious comedians of all races. And trust me, in person, the white comedians are probably worse with the racial jokes than the blacks. And the crowd at these clubs is VERY mixed with whites, blacks, and hispanics. (Not a lot of Asians though).

Cliff notes: Don't judge white comics by the watered-down PG TV specials. Go to some clubs and watch some ugly, bald, white comics who tell racial/sex jokes just as well as the blacks on TV.

EDIT: I just remembered that everytime someone is announced as having "been on such and such TV special", I usually cringe and figure they are teh suck.
