Riddle: A jester is on his way to perform for the king and is running late. He is carrying three balls and his hat. As he approaches the castles he notices he has to cross a bridge to get to the castle but the bridge has a weight limit of 160lbs. The jester alone weighs 155lbs, his hat weighs 1lb, and each one of his balls weigh 2lbs. He has to cross with everything at once because he has no time to backtrack. How does he cross without collapsing the bridge.
Answer: He places his hat on his head and begin juggling the three balls as he crosses. One ball is always in the air at all times so he weighs no more than 160lbs.
