The late comedian Grady Nutt (he appeared on "Hee Haw" from 1979 to 1982) had bit about growing up in a small town:
"We used to steal the S&H Green Stamps sign and put it in front of the funeral home at night. The next morning, everybody would drive past it, and there it was: 'We Give Green Stamps!"
Rumor has it, their sales spiked :)
