Most I've seen aren't "a little junk in the trunk" but more like the Jeff Foxworthy joke "like two Volkswagons trying to pass each other on a gravel road". The kind of people who can't bend their knees more than 5 degrees, usually have their legs wrapped up because of circulation issues. The kind of people who can't wipe properly anymore because of the size of their rear end. Mostly describing my late great-aunt here.
