There used to be some good shows for this sort of thing though many probably didn't air or at least weren't aired for long before getting removed though finding any one of those and the way the Tube works well...found this at least for a older Devil May Cry commercial which should be fairly tame compared to some of the other stuff.
i aint had a tv for about 14 years now but i remember you used to look forward more for the ads than the bloody programmes Although not funny the Rutger Hauer Guiness ads were great
