A head-on collision occurred between a man and a woman. Both emerged from the scene intact while their cars were totally demolished. The woman said, "This is quite a predicament. We should drink a toast to celebrate this miracle." The man replied, "What a great idea; I just happen to have a bottle with me." With this he handed it to the man. The man downed half the bottle and handed it back. The woman would not take it back and said, "I think I will wait until after the police arrive to celebrate."
