Last year I got these reindeer car antlers for my wife. This year she let me have them for my car. They look like this:
(Note: this is the picture from the catalog, not one of our cars.)
Tons of people stop, stare, and then break out in a smile or start pointing out my car to friends as I drive by with my sleek reindeer antlers and big red nose. The antlers slide onto your windows, which then shut securely. That means you don’t need to worry about antler-theft in a parking lot or losing an antler as you scoot down the highway at 65 miles an hour. You may need to pay attention if you roll down your window at a McDonald’s drivethrough though.
I ordered mine from What on Earth and they’ve worked great. Lots of fun and highly recommended.
