Ways to Annoy Nathaniel....
We don't have 50 yet, but considerably less than that. Please, if you have your own, submit them!

1. Disobey and contradict him.
2. Say you know his birth name.
3. take Kitty's form.
4.Send him a letter congratulating him on his engagement to Bartimaeus
5.Call him pretending to be Jane Farrar setting up a date, then laugh when he shows up and she doesn’t
6.Pretend to channel the spirit of Mrs. Underwood
7.Tell him his feet smell
8.When he does something you don’t like, ask what Kitty, Mrs. Underwood, or Ms. Lutyens would think
9.Tell him Bartimaeus should get workman’s comp
10.Sing, “I know a song that gets on everybody’s nerves…everybody’s nerves…everybody’s nerves…”
11.Do anything you suspect Bartimaeus would do in a given situation
12.13.Invite him on an episode of “What Not To Wear”
14. At some big event that is very important to his image, show the video of the Makepeace skit in which he was suspended on a trapeze in gauzy wings
15. Tell him that he and Makepeace are in competition for bad theatrics (mostly applies to first two books...)
16. If you’re a demon, go to him in Kitty’s form, pretend you’re in love with him and get him to declare his love for you, then turn into Quentin Makepeace and laugh.

Thanks to ValkarieRaven for the last 12!
