I cant believe you guys havent mentioned these adverts:
HI, MY NAME'S BARRY SCOTT, AND IM HERE TO TALK ABOUT CILLIT BANG... pisses me right off, but we take the piss at college, and the esure(the man, not the mouse) advert was fantastic :P
but for pure brilliance in Adverts, i always love Honda Adverts, the new adverts are great, and the adverts with the flying cartoony engines had a really good jingle to it trhat i kept humming to myself alot :P
