The real reason you get colds

This is a Listerine ad from 1932, claiming colds could be prevented by gargling twice a day with their product. Go here for the full text, which includes gems like "Wise eating, moderate exercise, ample rest are half the battle in warding off colds. The other half is the systematic twice-a-day gargle with Listerine, the safe antiseptic."

Hysterical. If only this were true!
