This bumper sticky gave me headaches when I first saw it in the early 80's. At that time no dictionary gave the information what horny meant...
Now I am a little wiser :-)
Unfortunately, this horn wasn't able to honk anymore:
Luckily, the Porsche has 2 horns. But the other horn had a loose connection, resulting in no noise at all when I hit the button. The other horn is reconnected now. Because sometimes you need to honk - for different reasons ;-)
