Two prostitutes

Two prostitutes were riding around town with a sign on the roof of their car which read, "TWO PROSTITUTES... $150.00." A policeman noticed the car, and quickly pulled them over. He approached the ladies and told them they'd have to remove the sign. Otherwise, they'd be arrested and taken to jail. Just then, another car passed by with a sign which read, "JESUS SAVES." The two ladies asked the policeman why he let the other car drive by without pulling them over. "Well, that's a little different since it pertains to religion." The two ladies were furious, but nonetheless they removed the sign and drove away. The next day, the same policeman noticed the same two ladies riding around town with a sign on the roof of their car. He figured he had an easy bust, so he pulled them over once again. As he approached the car, though, he noticed a new sign which now read, "TWO ANGELS SEEKING PETER... $150.00."
