A sentimental favorite of mine among all the great bits by the late, great George Carlin, from "What Am I Doing In New Jersey?", ran:
The most dramatic license plate of all has to be New Hampshire's, which says [solemnly] "Live Free or [Sam Kinison voice] DIE!!!"
Well, I'm certainly not going to move there. I get just a little nervous in any state where they mention death right on the license plates.
On the other hand, Idaho says [goofy old man voice] "Famous potatoes."
I guess those are the two extremes in thought.
It would seem to me that somewhere in between "Live free or die" and "famous potatoes" the truth lies. Probably it's a little closer to "famous potatoes."
