Top Ten Reasons Why the Hubble Telescope Isn't Working

In some article, somewhere, someone wrote that they wanted to see David Letterman's Top Ten List about what happened to the hubble telescope. Well, here they are:

10.    The guy at Sears promised it would work fine.
9.    Some kids on Earth must be fooling around with a garage door opener.
8.    There's a little doo-hickey rubbing against the part that looks kind of like a cowboy hat.
7.    See If you can think straight after twelve days of drinking Tang.
6.    Some bum with a squeegee smeared the lens at a red light.
5.    The blue prints were drawn up by that "Hey, Vern!" guy, Earnest.
4.    Those damn raccoons!
3.    Shouldn't have used G.E. components.
2.    Ran out of quarters.
1.    Race of super-evolved galactic beings/joksters are screwing with us again.

Also, just for an added bonus, Dave said: "...apparently, they can't get this telescope to focus... for that much money you might as well get the auto-focus."
