A blonde is on the bus when this guy gets on with both of his front trouser pockets full of golf balls and sits down next to her. The confused blonde keeps looking at him and his bulging pockets...

He notices her looking and eventually, after many such glances from her, he says, “It’s golf balls.”

Nevertheless, the blonde continues to look at him for a very long time, appearing to think deeply about what he had said.

After several minutes, she can’t contain her curiosity any more and asks, “Does it hurt as much as tennis elbow?”
