I've spent the last half hour or so, trying to keep a straight face lol. Friend tried to pull a prank on me, and I was trying to stall to compute the implications of pranking back, or just exacting a revenge... in various ways. He's so lucky I don't have a cruel nature. And if you are reading this, the thoughts I mentioned were only part of the possible retaliations that came to mind :-P
When you can look at something serious, and find about an 8-15% chance they're not trying to pull your leg, you know it is tempting... to not have a lot of sick fun with it at the pranksters expense. Some how, I think either I know some crazy people, or I'm just to kind hearted lol.
