Does anyone know...

Um, maybe directly to your forehead?

...no comment!

LOL. We were in a waiting room at a neurologist's office. The TV was on, and this commercial was played. We discussed how the commercial never really says what "Head On" does, but the consensus was that it is for headaches. People were laughing about the commercial. These were people many of whom had brain tumors (thank God, my daughter was there for migraines), so it was interesting that it gave them a chuckle.

Or maybe you put it on your forehead and it makes you smarter? Or dumber?

this commercial is on like every 5 mins on the weather channel around here

The headache goes away as soon as the commercial goes off!!!!!
