There's an advert I've seen recently on television which I think is the most painful one ever. I think there's 4 men side by side. The soundtrack cannot be comsidered as music as it seems to sound like dustbin lids being banged together combined with the screams of those in hell being tormented. I think it may be a pizza ad.
It's the only advert I've seen where I have to turn over, turn the sound down or leave the room. There should be a health warning given before the ad.
