I think people should either play the game properly and put specific ads not just "any financial services ad" etc, or not be allowed to play. So there!
The ones with sodding Joanna-mystifyingly-popular-Lumley and the "you don't have to be posh..." slogan. The one in the cafe was bad enough, then they followed it up with one featuring Ian f***ing Wright, one of the most stupid annoying people on TV.
Every single one of those Honda "The Power Of Dreams" ones - textbook cases of what happens when advert makers think they're SO artistic and disappear up their own rectums. The elongated one where there's a choir impersonating car noises is, in particualr, very annoying. Adverts like that, which go beyond about 25 seconds, would be banned under my administration. There are some sadly deluded people out there who think that choir ad is "clever". Don't listen to them, they're wrong, and it's stupid.
