Some of you may find this clip offensive. Some may laugh until you cry. If you are unfamiliar with Lisa, understand that she takes the piss out of everyone (gays, blacks, Italians, EVERYONE). This is the essence of what she does.
Comedians are not political activists or social workers. I think comics should throw all notions of political correctness out the window. Wit is important but censorship kills comedy. There. I can get off the soapbox now. ;)
