For your Dad's birthday, he some friends, your mom and uncle all went out drinking at the local Applebee's, you unable to join due to being only 20. Half priced app's and overpriced margarita's got everyone nice and drunk. Your parents and Uncle come home, and your parents attempted to have very drunk sex before passing out. Your Uncle however, comes and visits you in your bedroom while you're in bed. He has a story to tell you about how your parents met, and how your Uncle has a grudge against your father, that he is very intent on evening the score.
