This phone, according to their ad campaign (yes, the post title is a direct quote). Because “thinner than a supermodel” means that the phone is hot, because skinny things are always pretty. But we all know that hot-girl supermodels are dumb, and this phone is not dumb, so it’s easier to talk to than those model-types.
Pitch point: Skinny, hot. Skinny women, stupid. Skinny phone, buy it.
I’d like to say that I just found the dumbest advertisement of the day, but I think Amanda beat me to it.
