There is a Crest toothpaste TV commercial. A woman staring at a random guy, and her voice goes: “he could be the one, the father of your children… but first you have to get him to say hello”. Since the woman is not allowed to speak, she can only smile at the guy and hope her blinding smile will make him notice her.
Luckily I’m not the only one annoyed by this commercial. http://screaminginallcaps.com/2013/07/08/unlike-the-women-in-crests-commercial-i-can-use-my-words/
