I have always hated that HeadOn commercial...
"HeadOn Apply Directly to your forehead! HeadOn Apply... HeadON I CAN'T STAND your commercial but your product is amazing."
I saw HeadOn at our grocery store.
Jeez, what if someone had a headache and used HeadOn... but nothing happens? What if his/her headache didn't go away?

That'd be hilarious if that person went onto the commercial saying that the product didn't work.
