I was reading the July 1932 issue of The American Magazine over at the Comic Book + site, and learned some important medical news … I’ve been using Listerine all wrong!

Seems I’ve been gargling with the stuff all these years, when what I should have been doing with the product is dousing my hair with it and massaging until I can “feel the scalp tingling and glowing.”

Or, based on the photo above, having my loving wife massage my scalp for me.

Somehow I’ve got a feeling that won’t be happening …
