冷笑話：醉酒測試

　　A man is driving home, when he is pulled over by a patrolman for a broken blinker. The cop looks into the guys’ car and sees a collection of knives in the backseat.

　　“Sir,” the cop says. “Why do you have all those knives?”

　　“They’re for my juggling act,” the man says.

　　“I don’t believe you,” says the cop. “Prove it.” So the man gets out of his car and begins juggling the knives. At the same time, a car with two guys in it drives by.

　　“Man,” says the first guy. “I’m glad I quit drinking. These new sobriety tests are hard.”
