If a joke is tired and old, you can still pick out humor in it. It's possible to make a joke about George Bush being stupid that still manages to say something new or insightful and thus still be funny. But if it's just "ha ha bush is dumb and says words wrong" you are just going to be a sad little humorless nothing that makes people wonder "why are you doing this to us?"
So that's what we have here. As though the world did not yet have enough "ha ha windows vista sux" jokes. Not that they were all good, but the point is lame jokes about vista were everywhere. Two years ago.
Oh true we have one other element: Hitler. Dammit I am sick of hitler. He just gets stuck in as the default "horrible thing that nothing is worse than." There ought to be a law against it. And then a comic about that law.
This comic is a terrible stand up comic saying "hey guys I've noticed some differences between genders, I am going to list them now" and the audience is rolling their eyes.
