Annoying people is fun. The best way to annoy people is to hurt them, preferably severely and repeatedly. I picked kicking them in the shins, but an even better thing to do is stab them over and over. I guarantee that they will be annoyed.
Hum a lot.
Throw light objects at them (for instance crisps).
Eat all their food.
Kick them repeatedly in the shins.
Make them answer stupid polls (ahem!).
Send them junk mail/post.
