This guy was supposed to make a speech at a convention, but when he went to the men's room, he turned around to flush and at the same time he sneezed. Down went his dentures into the sewer. He went and sat down next to his host and told him what happened. he said "I can't speak in public without my teeth"! The man next to him pulled out a set of dentures amd said "Try these." he did, but they were too big, so the other guy says, ok try these". They were too small. But the third set fit well so he made his speech, and afterwards thanked his mentor saying, "I was so lucky to sit next to a dentist"! the mentor said, "I'm not a dentist, I'm a mortician."
