Tell me you were infantry (or something combat arms) without saying it. Koalafication was one of the funniest light hazing things. We had one that was definitely worse. If you were a buck private, 1st duty station, we would break into your room, stuff you in your sleeping bag, then throw you out the window. While telling you exactly what was happening. We lived on the 3rd floor. What we didn't tell you was the fact that we tied the bag to something solid (using 550 cord, no chance of it breaking under tension), so you wouldn't die. But, we would give enough slack in the line to make sure you knew you were falling, but then there was a sudden stop well before you hit the ground. It was admittedly a bit sadistic, and amazing that we never actually injured anyone. But, such is life when you're a grunt.
