Wheely down the Expressway

Want to hear about a Jackass. Today when I came home from school a guy decided to show off. I was driving and he came on a motorcycle next to me and then passed and went in fron of me. I didn't think of it until her stood up on the bike and pulled the bike up and did a wheely in the middle of the expressway. Of course he went around other cars and looked back to make sure that I was watching. I thought that the trcik was pretty cool, but at that moment in time was thinking "you jerk, do you want to kill your self". I wonder about people like that. Where do they pick that type of behavior from?
