Weird Signs on the Interstate

As I was driving back to Carlisle on Friday, I noticed some interesting signs on the Interstate. First was one of these portable construction signs that that said "Live EZ-Passes" would be available on January 13 from 7:30 a.m. until some other time at the PA Welcome Center. I think the use of the word "live" was odd. I mean, what were they going to sell? Dead EZ-Passes?! Maybe they meant that you could get your EZ-Pass on the spot, rather than waiting for it in the mail.
Another sign was a sign featuring Shrek, saying "Be an Ogre Achiever," and then "Pass it On." I could not see who was sponsoring it, although there was a sign that said "brought to you by..." I couldn't read it, and it was in extremely small type. My other favorite sign is one that says "Burgers Fit for a King, not a Clown"
