Have you heard any jokes with unexpected endings?

At the entrance of the hospital, the security guard was moved by a man and a woman. It was raining heavily and it was quite cold. The man put his coat on the woman. The woman took off her coat and put it on the man. The man put it on the woman again. "It's so cold. What are you wearing?" "Okay." After several back and forth decisions, the security guard was moved. At this time, the woman said: You should wear it. If I wear it back, how can I explain it to my husband?
