What’s the best prank in uniform you've seen? Comment below!

I'm going to post another one- In the artillery we had a rubber eye cup on the pantel-Panormaic Telescope. we would put shoe polish on it and get young Lt's to take a look. The ultimate goal was to get the person to use both eyes! We called it a Petey named after Pete the dog in the Little Rascals. when both eyes where had- a double Petey!

As a cadet, my AFROTC Detachment went on site visits. During one such visit, we did an overnight at Ft. Mede; the accommodations was an open bay barrack. At the end of the bay were rooms for the cadre (TI's, etc.) where there were a couple of beds; I snagged one. A number of my classmates were not very happy about that (poor babies).

That night I noticed that my bed was very neatly made, with crisp corners & etc. I never make the bed that neat, and suspected something. Sure enough, I was short-sheeted, and so I mitigated the situation and hopped into bed. Not too long after, one of my "friends" poked his head in and looked right at me. I know who he was and who his friends were. The next day, there were a couple of hours free. I knew in which of the bunks these folks slept.

So, I had their beds very neatly made, with crisp corners & etc.... (None of them were short sheeted.)

go find a st-1

Ours was something that we did for ALL new soldiers (Combat Engineer Unit in 3rd Cav @ Ft Bliss). We would take the final drive gear from an M-80 tank (This gear is about 3 feet in diameter, 1-1/2 inches thick and weighs about 90 pounds) and have him carry it all the way to the front gate of the motor pool under the guise that it is a special tool that Sgt. XXX needs. Once there, Sgt XXX would send him back saying, “I told him that I was working on it in the bay!” And then send him back to the bldg. We would send him back again, and back, until he finally got the balls to ask what the hell was going on - and then welcome him to the unit. After that is was the same that I am sure everyone does… send him out for a box of grid squares, a gallon of prop wash, a can of ground guides, etc.

At JRTC, we were attached to an Apache unit as support. The game hadn't started for us yet, so we were bored as hell. A buddy and I loaded up a 3 liter soda bottle with a bunch of MRE heaters, and slipped it under the 64 guys TOC. We thought it was a dud, but the extra large capacity gave us a LOT of time to get away. What seemed like Several minutes later, we hear it go off. BOOM! The radio traffic came alive, and they launched 2 Apache's thinking the Cadre were starting the game. Our old CO was one of the cadre there. He thought it was hilarious, and shared our story to the TOC. They weren't happy they were played by Enlisted guys.

We received a new XO on board our Submarine. Our Captain was the Prankster of the boat. I was the Auxiliarymen of the Watch when the Captain ordered me to cut off the hot water to the Officers shower. So underneath the Helmsmen feet was the access to the valves. You could hear him scream all the way Aft!!! The XO comes to the control room and the Captain says, "Yea I forgot to tell you about that little snafu with the Hot Water" Then while he had the Con, i took his door off and hide it in the engine room for a day. We called it PMS Door closures. Not Amused......

On fire watch taking everyone’s combo lock that was left open and locking them together in a giant mess and leaving it in the kill zone.

This one actually got a little out of control.

Young private new to the unit opened the door to the arms room and just walked in to get his weapon, and the armorer just about had a stroke. He decided to send this kid to the unit next door to get a box of blank adapters for an M-203. Fast forward several hours, and we get a visit from division, where the kid was trying to get access to the SCIF after people had sent him all over the post and he ended up at division HQ.

Too many to think of just one, but one that comes to mind was that nasty Blue Falcon who refused to bathe regularly.
One night (did I mention he had as much body hair as the fabled Chewbacca?), He (again) didn't bathe, and the smell was downright putrid.
He had a habit of falling asleep on his back, with that carpet exposed.
One of our platoon had this can of fractured and somewhat dried up kiwi.
Private Falcon had fallen asleep with a hand out, palm up.
Our hero donated a rather largish crust of that black kiwi to the cause, and placed it in Pvt Falcon's outstretched hand.
Someone else went in, and tickled Pvt. Falcon's chest hair.
The result was magnificent, as he smooshed the entire chunk into his chest hair.
It didn't take long before he felt it cooling and contracting in his chest hair.
I forget how long it took him to wash that stuff off, but he was never late to the showers again, lol

A few; but I'd need to be sitting down with a few beers in the ready rack.
