I have a motorcycle, and as such, I'm also a member of some motorcycle forums. This thread from a Suzuki GSXR (crotch rocket) forum has spread like wild-fire across the motorcycle forums. It was just too funny to not post here as well. Make sure you read through at least the second page; that's where it gets really good. I don't want to give away too much, but you guys will love it.
