It's not just the blonde Ladies either:-
Three business men were sitting in a bar, drinking and discussing how stupid their wives were. The first says, "I tell you, my wife is so stupid. Last week she went to the supermarket and bought $300 worth of meat because it was on sale, and we don't even have a fridge big enough to keep it in!"
The second agrees that she sounds pretty thick, but says his wife is thicker. "Just last week, she went out and spent $17000 on a new car," he laments, "and she doesn't even know how to drive!"
The third, a blond male, nods sagely and agrees that these two women sound like they both walked through the stupid forest and got hit by every branch. However, he still thinks his wife is dumber. "I have to laugh when I think about it," he chuckles. "Last week my wife left on a vacation to Greece. I watched her packing her bags and she must have taken at least 5 boxes of condoms with her. She doesn't even have a penis."
