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.
