How to piss off Naruto
Tell him ramen's illegal
Tell him his favorite ramen is out of stock(Better yet, all of them)
Call the Akatsuki and tell them that Naruto's weakness is ramen
Watch Naruto get captured the Akatsuki putting a bowl of ramen under cage tied to a tree, they cut the rope, it fell on him, and they (and you) laugh
Tell Naruto that Sasuke's waaaaaaaaaaaaaaaayyyyyyyyyyyy cooler than he is
Insist on calling Naruto, Fox-boy
Ask him how the Nine-tailed fox has been
Sing "Foxy Foxy" by Rob Zombie till it gets stuck in his head
Get a fox suit, put it on him, and make sure he can't get it off
Show him the Naruto/Sasuke yaoi and laugh when he faints
