Vanity Plates? Like if someone who loved to run wanted a license plate that reflected his or her love would that be weird? Would that be in the same category as those vinyl car families (don't be offended if you have one on the back of your car, people obviously like them)?
Stripes on people who have body fat? If someone was tired of her boring solid colored clothing could she reasonably wear stripes or would she be mistaken for a hefty prison escapee or maybe a pirate on shore leave?
And those are all my burning questions for the day.
