What are your favorite Military Pranks?

What is one of the best prank's you have either done, or heard of someone doing. Late one night while in Iraq 05', and training the Iraqi Army, we had our medic call in from our CP. She spoke with the SFC who was the RTO that night and told him that we found out what was wrong with our radio. We had her say that it was a simple fix and we only need some "B-A eleven hundred November's and some S-T Rings" Well this guy says "stand by" and went looking. About an hour or so later he surprisingly calls us back and said that he woke up 1SG who didnt have any and that he didnt know where they were and said to check with supply. He woke up supply and went digging through the connex of course to no avail... So we told him roger and we ended the transmissions, laughing our butts off of course. Well the next morning the OIC of our group, a MAJ, walks out of his door upon our return and sternly said, "you, you and you, COME HERE, RIGHT NOW!!" Thinking the worst of it, we walked in and stood at attention. He sits down across from us and pulls out a piece of paper. It was the 1594 from the night prior showing that this idiot actually LOGGED IN the BALLOONS and STRINGS... smh he busted out laughing and we all just lost it... funniest thing ever.<br>
