At the moment, its either....
That weird betting site advert where the background is green, and some gabby floating head guy is talking, usually appears near Horse shows on Channel Four gabbing about "Money cash garrenty".
The 'We Buy Any Car' where they play some annoying song where its all like "We buy any car thirty, we buy any car firteen, na na duh duh oneder star, we buy any car dot cohmmmm".
The porker has to be some phone advert where some fat guy screams Wonga! whilst his face is plastered on everything imaginable, women, mountains and even mario bros. (the last example was a blur, but i did remember an advert that parodies mario bros)
