Damp Dollar Bills

Remember when we were kids? We put a dollar bill in our shoes between sole and sock. Sometimes we had so many bills that it created a limp in our walk. Anyway, the lunch lady, 7-11 store clerk, or some other unsuspecting soul would get that wet, damp dollar bill in exchange for a candy bar or a slice of pizza. No sanitizer back then either. They just toughed it out.
