Buy a bunch of those stink bomb things. Not the ones that are in the packets but the ones that are like little glass bottles. I love just walking by an entrance to a resturant and breaking one of those right on the front door. LMAO, people sure think twice about eating there. There is countless things you can do with those. Throw one next to someone in a wheelchair. I like throwing them in convertibles.
I got caught throwing some in the cafeteria at my high school. Boy, did that suck.

 

Dang, you an evil sombeech, ain't you?
