My current three:
Big Brother et al
The biggest scam of the late 20th/early 21st centuries. The cost/benefit of the thing is astronomically attractive. A bunch of pampered, womenly men (thanks Lazs) discussing the emotional turmoil of being 25 years old and good looking, without the dignity to not chase bubble-headed, self-obsessed girls on national TV. The contestants are only marginally more bearable than the people who watch 24 hour cable channels covering the 'social experiment'; who hope to catch the idiots shagging or fighting, but they will never admit to that. Neither happens, and all they end up seeing is a bunch of people sleep or get drunk. Here's a thought, turn off the TV, go to bed yourself, get some friends around at the weekend and do it for real! Amazing!
Men's 'Lifestyle' Magazines
FHM, Maxim etc. I made the mistake of 'reading' one at a mate's house recently, to see if anything had changed since I last bought one. Basically soft porn with a few words as background. The scantily clad celebs say the same things - "I've never been with another women but I often think about it" or "I actually find ugly men attractive" or "I can't stay faithful, I love sex too much". They never say "I find lesbianism disgusting and I love my boyfriend and would never cheat on him." The stories are third rate tabloid trash, which might have got 50 words on page 25 of a regular newspaper but are drawn out to 1000 words of utter bollocks. Not cool. Buy a porn mag or open a book - both do their respective jobs better.

It just isn't.
