I also like how some categories show a lot of personality and you can tell the authors really care about the category and are "into" it.
There was one that I got a good chuckle about where they listed a car as a Don't Want. I can't remember the category off hand. For most of us, it's obvious that the car was not intended, but you'll always get that one wise guy who pushes the limits.
It was the Neon category......They showed a picture of a Dodge Neon as one of their "Do Not Want" items....
