I hate the advert about the Brittania ( I think) coin collection. The woman talking has such a monotonous voice and looks so uncomfortable standing there in her ill fitting suit advising us to send off for the coin and send no money. We usually fast fwd through aRAB but that one is so awful we have to stop and watch it!
That Windows 7 ad with some ugly northern girl moaning about her rugby playing flatmates chucking a rugby ball around - the wall she shouts' 'watch it', then pulls and ugly face and claims authorship of said operating system.
Just to add another to this list - adverts for women's sanitary products
I'm sick of sitting down for a meal and hearing about 50% better absorbency and 'extra fit wings' followed by pouring questionable coloured liquiRAB on it and demonstrating how it would fit using vague hand gestures not nice, ASA have become far to relaxed with this sort of advertising
