My Neighbor always seems to hang up his laundry on sunny days, but never on rainy days. One day I decided to ask him how he always knew which days to hang his laundry.
"Well," he explained, "if I wake up and my wife is lying on her side, I know it's going to rain and I shouldn't hang my laundry. If I wake up and she's lying on her front, I know it's not going to rain and I should hang my laundry."
"That's a very interesting method," I replied, "but what if she's lying on her back?"
"Ah, those days," he said, "I have better things to do than laundry!"
