The straight man can be funny too. Ricky Ricardo had some good moments, as did Patricia Castle on Home Improvement, and plenty of others. But the start of this conversation was about the recent trend of men being complete idiots on sitcoms, and I have to say, I don't even watch most of those shows, because if roles were reversed, and the women were portrayed as complete morons, the backlash would be brutal.
I equate it with the way women feel they can insult a man anytime they feel like it, and it's no big deal. Call them stupid, fat, lazy, whatever, it's just fine....Go ahead and say any of those things to a woman and see what happens. Double standard, pure and simple.
