Sign him up for anger management.…no one can deny he doesn’t need it
Force him to read about his death in Twilight. Cry and then laugh under your breath. Make sure he hears both.
Chase him around with garlic. Get Jacob Black to help.
Show him those love letters “Victoria” sent Edward.
Force him to play a game with you that you invented. Change the rules every 5 seconds so he loses.
“accidentally” sign him up for an Edward fan club. Force him to go to every single meeting.
lock him in a room with Edward, Jacob, Mike, etc and before you leave remind them about how James wanted to murder Bella. Watch the fun!
make him write fanfiction with you. Correct his grammar. Let people flame him and laugh when yours gets good reviews.
Tell him Victoria likes men who wear tutus. Buy him one; get all offended when he doesn’t wear it. Start crying and don’t stop until he puts it on. Video tape him in it and send it to the Cullens’, the Volturi, the Quileutes, Victoria, etc.
