What was your favorite field prank?

I already discussed what we did to our XO in Antarctica on another post. But sometimes roommates go after each other. Down on the ice, you develop habits. Mine was to wear my bedroom slippers to the shower, about face at the shower and butt first in so my shoes were ready to go when I was done. My roommate was a dentist. Ray decided to grab a hot glue gun and glue my slippers to the deck while I was in the shower. It worked perfectly with me walking right through them. "Ray you sonofa!!!!" Word gets around Mac Town and everyone loved to discuss my habits at the club. The only thing I could do is give them a new target and that target was Ray. Since I got up early every day, I'd crack open my Swiss Army knife scissors, go to Ray's locker, take his belt buckle off the belt and trim one rib and put the buckle back on. I did that every day. About 4-5 days in everyone noticed Ray wasn't doing deserts. A week after, he was absent for lunches. Everybody but Ray knew what was going on and it was tough containing all that high pressure. About the third week in, Ray comes charging into the mess hall carrying two belts "Ball you sonnaofa....!!!!". Ray got a standing ovation.

I had a Soldier make, and subsequently use, a 'Concertina File' to make sure our perimeter wire was sharp ;)

I asked a 2LT pilot if he had cut his grid squares for his flight plan. I almost had him convinced to cut up his map before my CW3 MTP chimed in over the intercom. Ahh the good times lol.
