What is the difference between a Harley and a Hoover?

Sadly, I did not write this, but I found it on Craig's List and was overcome with an irresistable urge to make sure as much of the world as possible has the opportunity to read it. Whoever the author is, I salute you:

ANSWER: On a Hoover, the dirt bag goes on the INSIDE!

(Sorry, Craig's List removed the rant. Probably some loser HD fans in CL's admin. Nuts, it would have been cool to have copied and pasted the whole rant, but I didn't realize CL would be so wimpy.) I must have received a dozen accusations that this was my rant and I was too gutless to sign it. If I could write that well, I'd have signed it.
