I've never seen this before-- antlers for your car. I wasn't too impressed, and as a matter of fact, the first thought that popped into my head was: oh, more crap for people to buy.
Then Youngest spotted it and said: "Look! A deer-car!!!"
Which then prompted a whole conversation with Daddy about who was driving the car (an old man and an old lady as a passenger), where they were going, why they had a deer-car and so on.
So now I think it's cute.
A deer-car. :o)
