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

I was a topographic surveyor. We were out to do a night shot. Use stars to fix a point. There were five of us and my buddy had a bad leg. We set up a tripod with a light and he was to stay with the 'target'. I told my Sgt that wasn't needed and he agreed, so I stayed with my buddy. This was Germany in the summer time. After they left I looked around and noticed that we were about 100 yards from a village gasthaus. We had a radio and fresh batteries for the light. So we agreed to put a new battery in, take the radio and go to the gasthaus. We went in in uniform and put the PRC on the table and ordered beers. Half way through the beer, the Sgt called on the radio and said they lost sight of the light. So, as we sat there I said "on, off, on, off, etc." He responded, OK I see the light. Another 10 to 15 minutes later he called back and said that he lost it again. So we left. My buddy with the bad leg carried the radio and I ran to the light. Flipping the switch on and off. The problem was my speed and my buddy's speed weren't the same. But anyway, they said they had the light. About every 15 to 20 minutes they called. I then turned the light out. And they would call telling us to turn it on and off and we would answer that we were, but not. They next morning when we were all together, we found out that they were in a gasthaus telling us to turn it on and off. Then I told them that we were in a gasthaus at the same time. The Sgt got pissed at us, but felt it was ok for them.

I grabbed a bicycle belonging to a practical joker and hung it in the rafters of the squadron warehouse.

Back in the day when I was a PVT with lots of time, we used the old shaving cream in the face trick, when the guy is sleeping put some shaving cream in his hand and then tickle his nose. He will invariably slap his face with the hand w/ the shaving cream and get the stuff all over his face.

Sending the new guy for squelch grease was always fun.

Three USAF pranks shared with me:

We'd send our new co-pilots out to get a bucket of prop wash or 6 feet of shore line.

We used to get the Airman Basic newbys that were working as medics on their first assignment out of school and we sent them to Central Supply looking for sterile Fallopian tubes.

Newbies were asked to fetch a bucket of steam, or a metric crescent wrench.
