Your grandpa may seem like an ideal wingman: he's two generations older, probably doesn't have the same taste in girls, and cant' stay up past 9pm, so the rest of the night is just for you.  However, I bet when this guy asked his grandfather to be his wingman, he didn't know his pop was such a smooth talker.  Before you ask your grandpa to help you out, make sure he doesn't have more moves than you do!
