My sister thinks she's sooooo smart. She said that the only food that makes you cry is onions, therefore I threw a coconut at her.

Alright, listen up, buttercup. This joke is funny because the person telling it is a doofus. The sister says onions make you cry. So the not-so-smart sibling chucks a coconut at her. It's unexpected and kinda violent, which is why it's funny, even though you probably didn't get it at first.
