Okay, so I have a little story. My brother is 23 and I'm 13. When we were little kids he always used to play tricks and pranks on me, and he still does. Constantly. I'm sick of him thinking he's better then me and I need to hit him back with a good practical joke, but it can't harm him because I don't want him getting too pissed. In the past, he's colored my whole face with brown permanent marker, put pretzels in every pair of my socks, put baby powder in my hair shampoo, gave me crazy glue as lip gloss, and not to mention lighting fireworks in my room as I was sleeping.

I appreciate every answer! Thanks.
