A man got on the bus with both of his front trouser pockets full of golf balls, and sat down next to a beautiful (you guessed it) blonde woman.
The puzzled blonde kept looking at him and his bulging trouser pockets.
Finally, after many such glances from her, he said, “It’s golf balls”.
Nevertheless, the blonde continued to look at him for a very long time, deeply thinking about what he had said.
After several minutes, not being able to contain her curiosity any longer, she asked; “Does it hurt as much as tennis elbow?”
