A juggler, driving to his next performance, is stopped by the police. "What are those machetes doing in your car?" asks the cop.
"I juggle them in my act."
"Oh, yeah?" says the doubtful cop. "Let's see you do it." The juggler gets out and starts tossing and catching the knives.
Another man driving by slows down to watch."Wow" says the passerby. "I'm glad I quit drinking. Look at the test they're giving now!"
This joke was told @ Smokin' Joe's Cafe
