1. Chalk screeching on a blackboard... I think this doesn't need explaining.
2. Overt shows of affection in public places - also known as groping, snogging etc. frankly, I just don't want to know
3. Pop Idol and other such programmes
4. Matthew Kelly - get off the TV, you are not funny
However, "The Office" makes me cringe in a positive way... I think I spent more time cringing during the Christmas specials than laughing.
