According to the quiz at Am I Annoying.com, I am moderately annoying (hurrah! I wouldn't want to be completely bland)
You can also vote there for the annoyingness of celebrities. Alas, Trinny and Susannah (two of the most annoying celebrities on the planet) are not on there. They do have historical figures on there, though; for instance I just voted the Emperor Constantine as annoying for embracing Christianity and making it the state religion of the Roman Empire when it was much better as a rather subversive non-statist little cult. You can also find new people to get annoyed about that you'd never even heard of, like Charles Taze Russell, founder of the Jehovah's Witnesses. Just for balance, I also voted Richard Dawkins annoying. It's a pity it's just a straight choice between annoying, not and don't care, as for some people (like Constantine, and Henry VIII) I'd like to rate them as extra annoying. Humph, Henry VIII isn't on there, but both his daughters and his dad are. I'm annoyed with his brother as well, for dying young and letting Henry VIII get the throne. He caught a chill in Ludlow Castle, or something. I once had the satisfaction of going up to his tomb and telling him that I was annoyed with him for dying early.
