Ooh!
Forgot to mention Comet - bastards in customer service, after sales, the lot. Washing machine broke down when DD was two months old and it took them 4 MONTHS not to fix it - endless call outs, endless repeat breakdowns, callout times always two weeks from the time you called them. The machine was just a gnat's whisker over a year old and they refused to refund it unless it was on one of their store gift cards, so the replacement we got is still under their care :(
The Daily Mail - Aside from the obvious reasons, I frequent a photoshopping/humour website that will produce a lot of very very funny material, a lot of which you've probably seen in viral emails. The DM comes onto the site every so often and just rips off a page's worth of pictures, crops off all the 'watermarks' (showing who originally made it) and publishes it as their own work. We (as a site) challenged them about it from a legal point of view (intellectual property theft) and basically they just said 'well you published it online you must have wanted it to be seen.' The usual creators of the really good stuff (not me I must add!) have now taken to putting their watermarks in the middle of the image...
In the Bloody Sodding Night Bloody Garden - Niece loves it, when DD started to pay attention to the tv I put an episode on for her. Utter tripe, I couldn't believe how awful it was. Won't put it on now, DD would much rather watch Tom & Jerry anyway. Which brings me to...
'Fake' Tom & Jerry - by which I mean ANY T&J not made by Hanna & Barbera. The Chuck Jones-era ones were bad enough, but the T&J Tales tripe will NEVER be shown in this house, nor any of the movies.
Also anything involving Ricky Gervais, can't stand the smug git 
Hm, I feel strangely better now...
