Seems God was just about done creating the universe, had a couple of left-over things left in his bag of creations, so he stopped by to visit Adam and Eve in the Garden.
He told the couple that one of the things he had to give away was the ability to stand up and pee. "It's a very handy thing," God told the couple who he found hanging around under an apple tree. "I was wondering if either one of you wanted that ability."
Adam popped a cork. He jumped up and begged, "Oh, give that to me! I'd love to be able to do that! It seems the sort of thing a Man should do. Oh please, oh please, oh please, let me have that ability. I'd be so great! When I'm working in the garden or naming the animals, I could just let it rip, I'd be so cool. Oh please, God, let it be me who you give that gift to, let me stand and pee, oh please........." On and on he went like an excited little boy (who had to pee).
Eve just smiled and shook her head at the display. She told God that if Adam really wanted it so badly, and it sure seemed to be the sort of thing that would make him happy, she really wouldn't mind if Adam were the one given the ability to stand up and pee.
And so it was. And it was...well, good.
"Fine," God said, looking back into his bag of left-over gifts. "What's left here? Oh yes, multiple orgasms..."
