I wonder what the deal is with signs made up of interchangeable letters.  Do they come in a box with only one full set of letters, so business owners (mostly fast food places) are forced to create words with numbers and upside-down letters?  And if so, how expensive would it be to simply go out and buy another set of letters?  Better yet, why not buy a set of Wheel-of-Fortune-inspired letters that are found in common words (i.e. R, S, T, L, N, E)?  I swear, sometimes I think the world would be perfect if people would just appoint me to be king. #products
