There Is A Line Where Enough Is Enough And We Have CLEARLY Crossed It!
People nerd out their cars. Long time ago, I drove with a couple of small Teenage Mutant Ninja Turtles on my back deck. Later, I drove with a couple of Pikachu on my back deck (which had the added benefit of making my common model car easier to spot in the parking lot). I'd probably do something with mermaids or My Little Pony if I could, a gentle nod that makes people smile or makes them wonder about me.
