Crimes of Carelessness

From the "Weird Al" Yankovic - Live! DVD:

Bicycles are also very dangerous - you could break your neck.

If you have to ride a bike, make sure to ride it really, really slowly.

Or better yet, why not turn your bicycle over and peddle it upside down.

It's also a good idea to check for bombs planted by Commie spies.

Make sure you wave hello to pedestrians before you run them over.
