There were three women who always hung their laundry out in the backyard.
Two of the women noticed Lucy never had her laundry out on days that it rained.
One day, they were all out in the backyard putting their clothes on the line when one of the women said to Lucy, “How come when it rains, your laundry is never out?”
“Well, “said Lucy, “when I wake up in the morning, I look over at James. If his penis is hanging over his right leg, I know I can hang out the wash. If his penis is hanging over his left leg, I know it’s going to rain, so I don’t hang out the wash. “
“What if it is pointed straight up?” asked one of the women.
“On a day like that, I don’t bother with the laundry. “
