"Let's stop at the next restaurant," said the optimist. "Then we can take the next bus and continue our journey."
"I don't think that's a good idea," said the pessimist. "It could cause something bad to happen."
"Or it could cause something good to happen," replied the optimist, "and besides, I'm hungry!"
So the two of them left the bus and went into the restaurant.
While they were eating, a news report came on the TV.
"A bus was crushed in an avalanche fifteen minutes ago," said the reporter. "Everyone on the bus was killed." The optimist and the pessimist recognized the bus as the one they had gotten off.
"See?" said the optimist. "I told you something good would happen if we got off the bus!"
"Good?" sputtered the pessimist. "If the bus hadn't stopped to let us off, it might have missed the avalanche!"
