I have come up with an awesome prank to get back at Jack for what he did to me (Two words: Rick Roll).
I am going to make him a CD of all Justin Bieber songs. Songs like "Baby" and his bad version of "The Little Dummer boy. I will put them all on a CD and give them another title -- like The Beatles, or Gavaroc's Greatest Hits. Then when he goes to listen to the CD, it will be Bieber! Jack will freak out, and I will have the chance to use my evil laugh!
I just need to get the songs and ask my Dad to put them on a CD.
