ok, get like ten of those powerball tickets , Then give them to him and tell him that you got them from a really good friend and that they are totally up to date. Also tell him that these are special tickets that cost more money, but have a better chance of winning. After he goes home that night, get an adult with a really deap voice to call him. Have him tell him that he's been watching him and he has special tickets and they were stolen from him and he wants them back. Make him sound like a gangster or a really bad person so he tries to say that he got them fron a friend. Then, have the really deep voice guy say hes going to come beat him up because he "knows where he lives", then, have the guy say hi's "people" are already coming to get him. Make sure your at his front door step listening in on the call. Right after the guy hangs up, knock on his door. He will get so freaked out that there is really people coming to get him. When he opens the door, surprise him! He will be so shocked! Trust me, this prank is really funny!!! I have played it on my friends before and they totally freak out!!! But they love it at the same time!
