You ever crap in someones pillow case!!! Now that is funny! .....also leaving open cans of sardines in vehicles was always good for a laugh. The concussion grenade followed by the CS in the center of camp always made me smile...as long as I was in on it! Being the Platoon Sgts Gunner, I usually was.
Ah yes, all in good fun. Using up the rest of the Smoke at the end of an FTX always got interesting as well. We used to tie people to their cots/bunks w/ 550 cord too. Oh yeah, one time, we took two ratchet straps, put them completely around the cab of a Hemmit while the guys inside were sleeping (the doors were strapped tight, w/ the mirrors folded in covering the window openening), and then pouned on their doors and watched them try and get the doors open, and roll down the windows trying to squeeze out around the mirrors... too much fun...
