When you wish upon a star, your dreams can come true. Unless it’s really a meteorite hurtling to the earth which will destroy all life. Then you’re pretty much hosed no matter what you wished for. Unless it’s death by meteor.

Now every body sing....(To the tune of "When you wish upon a star")

When you screw upon a car

Just remember where you are

If the motor still is hot, you'll burn your ass

If your hard on makes her scream

Cops might be called to the scene

When you screw upon a car

You don't need gas

If wishes were horses beggars would ride.

And if elephants could fly, that'd be one big phuckin' bird!
