I saw a bumper sticker on a Pantera once that read:
All of the parts you see falling from this car are of the finest Italian quality.
Back when I was living in North Carolina, I saw a licence plate on the back of a civic that read:
Vafancul
Being of Italian descent, I realized that this is Italian for "Go F*** Yourself. I think because it was in NC, where there weren't alot of Italian-Americans, nobody really knew what it meant.
