Security Troops in the Air Force were the worst on pranks.
One that I saw (Never participated :)) was breaking open a chemical lightstick on a nuke storage structure lock. When a newbie came along and shook the lock, he would have a glowing goo all over his hands.
His partner would immediately advise him that he was screwed and tell him to get his gas mask on ASAP. By the time everything was done, the newbie was waiting in the vehicle entrapment gate in his under pants, socks, boots and gas mask waiting for the fire dpeartment to come and decontaminate him with the firehose. This was all of course done during late fall.
The best "prank" I ever pulled in the Air Force was I beat a guy at backgammon for $200. I let him "work off" the money he owed me, otherwise I would have gotten nothing. I was living in the barracks at the time.
I had him ironing my cloths and shining my shoes. Then I started hiring him out as my "house boy" to others. He got real mad...he was like my personal servant. Everyone in the barracks got a good laugh out of me having a house boy.
