I don't have anything against bikes, but a lot of guys do stupid stuff on them to impress the girls and the ricers. If you cruise around at night and manage to get stopped at a light with a biker (meaning he's not driving 110mph next to some 16 year old girls in an eclipse), they usually look around to see what kinda chicks are around to impress.

They don't necessarily do it to themselves; it's everyone else's fault for thinking bikers are sooooo cool.
