You big meanie!! I remember sneaking into my brothers room (he was 9 yrs older) to record him talking in his sleep. I was at the foot of the bed hiding. He proceeded to grumble about how I was getting this new bike for my birthday etc and at the time that was my DREAM.
Well my birthday was a few days later. I opened all my presents and waited excitedly for the grand finale that never came!!
So I got even. I went into his room and found where he hid his bong. I brought it out to my mother one day playing dumb and saying "Mom what's this? I found it in Mikes room"
He has never pranked me since!
