Golf Balls

A man entered the bus with both of his front pockets full of golf balls and sat down next to a beautiful blonde.The puzzled blonde kept looking at him, his lap and his
bulging pockets. Finally, after many such glances from
her, he looked down and said, "It's golf balls".

Nevertheless, the blonde continued to look at him for avery long time, deeply thinking about what he had said.

After several minutes, not being able to contain her curiosity anylonger, she asked; "Do they hurt as much as tennis elbow?"
