Sometimes women will say, “You can tell how good a man is in bed by how good of a dancer he is.”
I've always been offended by that because I can't dance at all, but that has very little to do with why I'm bad in bed. There are a lot of factors to consider; pressure to perform, personal insecurities, terrorism, O.J. is still running around and such.
Anyhow, my reaction to that shallow expression is to develop one of my very own, which is this:
“You can tell how good a woman's going to be in bed by how poorly she gets along with her father.”
Did she just mention a forgotten birthday? Hang on to your hat buddy, she's humping for approval.
