One day, while on vacation, a man was captured by a crazy robber. The robber put the man in a net and hung him from a tree with a rope. The rope went over a branch and was tied to a stake in the ground. The robber put a burning candle under the rope near the stake. When the candle burned through the rope, the man would fall from the tree. It just so happened that a tiger showed up and waited under the tree. The man was very scared and thought about what to do.

　　Q: What do you think the man did to save himself from being eaten?

　　A: He sang the“Happy Birthday”song to the tiger, and the tiger blew out the candle.
