A commuter, sprawled out on a subway seat while reading a paperback, left the woman next to him with little room. When she asked him to move over, he refused.
A man sitting opposite them then yelled, "Why don't you sit like a human being!"
"What are you going to do if I don't?" the commuter retorted.
"Well, for one thing," the man replied, "I'll tell you how that book ends."
