Alain Prost button?

While I was waiting in line at a German film festival, I saw a couple of ladies with these "Prost" buttons. I thought, Is famed F1 driver Alain Prost running for city council? No. Apparently, this country bumpkin didn't realize that "prost" means "cheers" in German. The festival had a number of buttons for sale with random German words. I got this Prost button in exchange for a small donation to the Chilean earthquake victims.

Prost!
