At the moment I particularly like the Werther's Original one with the lad in the car telling his dad about the latest gadgets his friend has. The dad says he is looking forward to meeting the friend's dad at the school sports' day and the lad says...'Oh, he wont' be there, never is, he's more of a virtual dad'.
I like the way the dad smiles when the lad says...'Not like you....can't get rid of you!'
Favourite recent/current ad - I think it's for a Mitsubishi... Going over various terrain, it transforms into a (I think) panther, spider and crocodile. Obviously I know the vehicle won't really do that but the effect is good.
