Being a straight white male, or so he says, Seth can't make jokes about black people or lesbians without the possibility of offending so he brings on to joke writers who are black and lesbian.
That's one way to do it and the jokes are decent. At least we can all be thankful that he lays off politics for a while.
A lesbian couple was recently asked to leave McDonald's after an employee told them they were being inappropriate ... you'll have to watch the video for the punchline - lol
