Supposedly the "Papa, Nicole" idea was taken from an adult movie that the creative team had watched before having the idea for the advert. Two characters in the film are fornicating and on climax the female character says "Papa" to the reply of "Nicole".

I like this very much.

More adverts should have pornographic origins.
