This 1970 commercial provides so much insight into the polyester era's dating habits. Apparently, to snag a man, follow this woman's lead by obviously dropping your scarf on the ground. Susan here is all smoove-lovah until she thinks she might have dandruff. The horror! Fortunately, all you need to do is shampoo your hair outside of the shower, and then you'll be playing Drop the Kerchief all night long. Cue the sexy jams.
