How to piss off Tobi
Steal his mask
Give him a hockey goally mask
insist on calling him Jason(Friday the 13th) all day till he goes insane
Tell him that his mask looks like a lollipop
Put a sign on his back saying "I'm a retarded boy"
Watch everyone(and you) laugh when he can't find out what's so funny
Steal: Hidan's Scythe, Kisame's sword, Kakuzu's Threads, Konan's paper, Itachi's prescripted glasses, Zetsu's fertalizer, Deidara's clay, and Pain's Pierceings
Give them to Tobi
Tell them Tobi has them
Laugh till you pea yourself, faint, and being rushed to hospital watching Tobi getting his ass kicked and scared for life by the other Akatsuki members
