I used to date this fat chick who always complained when I did a wheelie. When I tried to explain to her that it was caused by all the weight being on the back of the bike she broke up with me.
Actually that made the bike a lot faster. I didn't have to stop as much to refuel her.
And there is this issue too
The guy who invented the first wheel was an idiot -
the guy who invented the second one... he was the genius!
