The Joke's on me..

I conjured up this big joke/prank yesterday and I was so proud of it. I even showed my friends my handiwork and was so sure it would work! and it did.. it worked so well that the victim of the said prank had no idea that it was a joke until late this afternoon... and now I have to pick up the pieces and show responsibility for my prank. DRAT... so much for having fun... coz now the joke's on me. ;(
