Fred was late getting home after his usual Saturday morning golf game, and his wife grilled him as to why.
Fred told her, "Well, I was on my way home, when I saw a lady standing by a car on the side of the road with a flat. I stopped and helped her change her tire, being a good samaritan and all that. I got fairly dirty from the job, and she mentioned that she lived just a couple of blocks away, and that I could wash up there.
"I followed her home, cleaned up, and thankfully drank the beer she offered me. Well, one thing led to another, and I ended up sleeping with her, and that's why I'm late getting home. I'm very, very sorry, but I'd rather be honest with you."
His wife stared at him for a moment and said, "You sonofabitch, you played a second round of golf, didn't you!?!"
