Got pulled over because of my personalized plate.

I just got this a couple of weeks ago. I was driving through Mississippi and got pulled over by a State Trooper. His reasoning for pulling me over is he's never seen an apostrophe on a plate before. The frustrating thing is my registration doesn't show the apostrophe on it either. I had to point out the spacing between letters to prove it wasn't drawn on. If it happens again I'm going to have to get a different plate.
