A juggler driving to a performance was stopped by a policeman. “What are those knives doing in your car?” asked the officer.
“I juggle them in my act.”
“Oh yeah?” said the cop. “Let’s see you do it.” The juggler began tossing and juggling the knives.
A guy driving by saw this and said, “Wow, am I glad I quit drinking. Look at the test they’re making you do now!”
