Golf Balls

 A man got on the bus with both front trouser pockets full of golf balls and sat down next to a beautiful (you guessed it) blonde.

 

The puzzled blonde kept looking at him and his bulging pockets.

 

Finally, after many glances from her, he said, "They're golf balls."

 

The blonde continued to glance at him for a long time, thinking deeply     about what he had said.

 

 After several minutes, not able to contain her curiosity any longer, she asked, "Does it hurt as much as tennis elbow?"
