I was about 4 watching the Naked Gun movie, and Leslie Nielsen instructed someone to stick their middle finger up. I had no idea what it meant, but seeing as how everyone laughed at that scene, I kept doing it to everyone because I thought it was supposed to be funny. Everyone kept telling me not to do it, but since they couldn't explain to me why it was bad, I just kept at it.
