There are a few people around town that think their vehicle is a reindeer. You probably have the same in your area. Having clip-on antlers and a red "nose" in the grille doesn't mean you can "fly" down the highway, or pull a red trailer any better.
I'm not Scrooge-ing it up after Christmas, it just drives me nuts on a few levels: added drag is one. Another, is forgetting that said antlers are held-up by a window, and inadvertently rolling it down will result in unintentional removal, and possible damage to following vehicles (or delays by picking it up)
Then there's stick-on eyelashes...
