As Creativereview noticed the playface commercial isn't the first one to do photographs of peoples faces as they react to stuff. Not sure if the Playstation ads were meant to look like sex, but some of the expressions do. (And imho the whole sex-angle makes it funnier, to me)
Creative review reckons it reminds them of Coco De Mer & Trojan campaign that we badlanded here previously. There the photographs are based on portraits taken at the moment of climax.
But wait.. there's more!
