I'm brain dead and have no ideas of what to do for either of my mulit-chapter stories, and bored, so I wrote this. Note: Yes, I do ship Murtagh/Nasuada.
31 Ways to Annoy Murtagh
1: Tell him he needs a haircut.
2: Forge love letters to Nasuada and pretend to find them in his shirt pocket.
3: Ask him if he is emo.
4: Even if he says he is not emo, call him emo anyway.
5: Read Eragon/Murtagh slash very loudly in his hearing.
6: Take him to see Twilight.
7: Paint "Team Edward" on his favorite shirt.
8: When he finds the shirt and asks you who did it, tell him Thorn did.
9: Write 'I love Eragon' all over his walls in permanent marker.
10: Show it to Nasuada.
11: Dye his clothes pink.
12: Call him Mr. Emo Man instead of his name.
13: Or give him a really stupid nickname.
14: Tell him that his new title is 'Emo King'
15: Attack him with a paint gun.
15: Sing opera very loudly when the lights are off, and when he turns them back on, look around curiously. Do this every time the lights are off.
16: Drink highly caffeinated pop and eat all candy in your house. Run at him and scream something about pink elephants.
17: Tell him he is just like his father.
18: Get him drunk.
19: While he is asleep, give him a makeover.

21: Slip ice cubes down his shirt.
22: Spy on him when he bathes.
23: Put him in a coffin when he is asleep. Pretend not to notice when he wakes up and cry about how much you loved him.
24: Replace all his underwear with thongs.
25: Walk in on him. Naked.
26: When you 'realize' he's in the room, scream, pull off his shirt, and put it on.
27: Put bows on Thorn and tell Murtagh that Thorn's new name is Princess.
28: Pretend to fall asleep in his room. When he finds you and tries to wake you up, curse at him and throw things.
29: Dress up in his clothes and say dramatically, "My name is Emo King! I have a sword! Please, somebody, I NEED TO GET LAID!"
30: Put rabbit ears and ask him if the bunny is cute.
31: Sing any annoying song you can think of. Constantly. Tell him it is now his theme song.
