Cheating on each other
A guy went out on a blind date and scored a hot one. Once they climbed into the back seat, she demanded it again and again! At first, he was happy to oblige, but he soon wore down. "I gotta take a leak," he said. Once he was out of his car, he noticed a guy changing a flat tire down the block a ways. He ran over and told the guy, "Look, buddy, I've got a gal in my car and we've done it at least five times and she still wants more. How about if I change your flat for you and you take over for me for a while?" Deal! They swap, he got the tire changed, had a smoke, kicked back, listened to the radio a while, but still his car kept bouncing up and down. Suddenly a cop pulled in, knocked on the steamed-up window and shined his light on the amorous couple within. "What's going on in there?" he shouted. The substitute said to the cop, "I'm making love to my wife." The cop asked, "Why don't you do that at home?" And the guy answered, "To tell you the truth, I didn't know she was my wife until you shined that light on her!"
