Tell the funniest joke.

Once, many animals took a boat together, and the boat lost its balance because of its heavy weight. Everyone decided to tell a joke. If one person doesn't laugh, the joker will be thrown down. The giraffe told a very interesting joke first. Everyone was very small except the pig. The little monkey told a more interesting joke, but the pig didn't laugh and the little monkey was thrown down. After a while, the pig was thrown down.
