What pranks were played on the new guy back in the day?

I showed up to my tin can and the Chief sent me off to SERVMART for a squeegee sharpener. The look on his face when I came back with one was epic. There were the standard ones of getting a jar of relative bearing grease or 100 feet of chow line. Sometimes the fracking goes the other way. I was sweeping underneath a fixture on the deck when the Skipper asked what I was doing. "Just cleaning under the BRT sir!". "Carry on." Chief overheard and asked what the hell was "BRT". "Big Round Thing Chief!"

My favorite was getting 4 Stars on the Honor Roll which was in the Head. Back in the day, the toilets were simply a plank with holes and a seat over a continuously running salt water trough. Early upgrade put partitions in, but it was still a trough. I'd wait in the upstream stall for the FNGs to come in and plop down. I'd make a newspaper float, light it, and float it down stream. If you got four butt singing yelps, you're a hero. Name on the wall; there you go.

As a young RM3 fresh out of A school at NCTAMS WESTPAC Guam, I was sent for a box of line feed. Little did my Watch Officer know that I was a fleet returnee before A school, having been a Deck Seaman for 2 years so I already knew all the tricks. I didn't let on and went back to the barracks and took a 2 hour nap before I came back and said "Sorry RM1, I can't find line feed anywhere!!!" He then told me what line feed was and I successfully acted like he got me! ;)

from the air force weather school not that long ago: the new guy was told to go outside and collect air samples for analysis. He went outside once an hour, every hour for 8 hours to fill a large black trash bag with air. He would then pin it up on the large bulletin board for future analysis. The next day, the NCOIC would be making his rounds and come across 8 trash bags pinned to the bulletin board for no apparent reason. unbelievably hilarious to witness.
