I use a large cloth bagfor groceries. One day a guy behind me said something to his wife about "look at the tree-hugger afraid to use paper or plastic,thinks she's saving the planet". I didn't say anything, just held the bag towards him which reads in big blue letters: Try Viagra!! (It was a freebie from a pharmaceutical rep) Everyone in line had a good laugh but he'll probably never look at a cloth bag and try to be cute about it again.
