A woman in a Porsche, as it happens, was pulled over for speeding by a California Highway Patrol motorcycle officer.
When he walked up to her window and opened his ticket book she said, "I bet you're going to sell me a ticket to the Highway Patrolman's Ball."
He replied, "No ma'am, Highway Patrolmen don't have Balls."
There followed a moment of silence while he realized what he'd said and she tried not to smile.
Then, without a word, he closed his book, got back on his motorcycle and rode away.
