Putting Out The Candles
My friend went out to dinner with his girlfriend last year and went to a really fancy restaurant. You know, the ones with dimmed lights and long candelabras with lit candles. The waiter served them wine, and he reached for his cup. He did it a little too fast and knocked over the candelabra. The thing fell over and set fire to the tablecloth.
The waiter came soon after that, and he was probably a guy not trained in handling fire extinguishers. He squeezed the trigger, and a mass of foam enveloped the table, including my friend and his girlfriend. Needless to say, the dinner was ruined. No one was injured though.
