I can't speak for the Jewish population, but I attribute my sense of humor to the tragic moments of my life. The best way to overcome certain tragedies is to develop a thick skin and sense of humor about things. Of course, I am very politically conscious and careful about my comedy. But when I do push an envelope, it's with a purpose.
First, it was a big deal for girls to dress more like guys. Then it was a big deal for straight men to be metereosexuals and care about their appearance in the way that a gay man would. Now we have to take it a step further - men should be able to not wear men's clothes if they don't want to.
