Sister memes

My sister thinks she's so smart. She said, "Onions are the only food that makes you cry." So I threw a coconut at her.

My mom said, "Take out the trash," and I said, "Okay." The next day she asked, "Where is your sister?" and I said, "In line to get crushed."

A brother and a sister always got into fights. One day the brother tells the sister, "You're adopted!" The sister yells back, "At least they wanted me!"
