People who can't distinguish between 'their', 'there' and 'they're'.
Any error message from Microsoft, as they are all useless!
Politicians who, instead of just thinking to themselves that we are stupid, rub it in our faces by releasing something that anyone with a brain could see was obvious, and is usually obviously wrong!
Any of those "research says..." items released by people with a Masters degree in the Bleeding Obvious awarded by the University of Absolutely Nowhere. (And are often later proved to be wrong!)
People who can't count to three!!!!
