Seems God was just about done creating the universe, but he had two things left in his bag of creations, so he decided to split them between Adam and Eve.
He told the couple that one of the things he had to give away was the ability to stand up while urinating "It's a very handy thing" God told the couple, "and I was wondering if either of you wanted that ability." Adam stood up and blurted "Oh give it to me! I'd love to be able to do that. It seems the sort of thing a man would do." "Please give me that ability, It'd be so great. When I'm working in the garden, or naming the animals, I could just stand there and let it fly, It'd be so cool. I could write my name in the sand. Please, God, let it be me you give the gift to, let me stand to pee, please." Eve just smiled and said if Adam wanted that gift so bad he could have it. It seemed to be the sort of thing that would make Adam really happy, and she didn't mind if Adam were the one to get this ability. Adam was happy and proceded to wash down the bark of the nearest tree, laughing with glee all the way. "Fine" God said, looking into his bag of leftovers. "Whats left here?" "Oh yes... Are you interested in multiple orgasms Eve?"
