Way to rub that cousin thing in, bro.

It's really not that hard to pick up a chick, guys. Soften her up by talking to her for a while, then ask her name. It's a rookie mistake to ask her name up top! Ease her into it. Okay, time to make sure she is not your cousin. If you need to excuse yourself and call your mom, don't be shy. It's better to find out now that mom has a brother she never talks to than on your wedding day to the chick.
