Every single I see this advert, I'm amazed at how brilliant just a single bit of conversation is. It's probably my favourite bit of marketing ever.

Person 1: *spots Head and Shoulders*

Person 1: "I didn't know you had dandruff?"

Person 2: "I don't."

Is it weird that I find that absolutely brilliant? If you have dandruff (luckily I don't), then what better way could you have a product marketed to you?
