A guy and his girlfriend were walking in the park one day when the guy says, "Oh, shit, I've got to pee, but there's nowhere to go."
"Why don't you go behind the tree?" the girlfriend suggests.
"Ok, I'll be right back," he responds.
About fifteen seconds later, he comes running back.
"You done already?" the girlfriend asks.
"No," the guy says, "I had pulled down my pants when I saw a squirrel looking for nuts. He saw me and I ran."
