What's the funniest joke you've ever seen?

I went to the kindergarten to pick up my daughter yesterday and brought a bunch of bananas. Daughter gives one to each child. A young gentleman peeled a banana and threw it into the trash can by mistake. He looked at the skin in his hand. I quickly gave him another one. After thanking him, Zheng Tai explained: He likes to eat after peeling. I said, then help him peel it. Then I fought back the pain in my liver. He handed the skin to his son and threw the banana into the trash can. . .
