I had actually been getting paid for LTJG for 3 months, but the XO liked having a Bull Ensign around to cause mischief, which was right up my alley..
I checked into my first squadron as an ENS while on deployment. The AIO was the Bull and had been looking forward to my checking in for a long time so she could hand it off to me (being the "senior" ENS....). The squadron was split site Misawa & Adak. I got off the MAC flight at 0900 was picked up by my sponsor and asked "do you want to go to Adak in 3 hours? Your new crew is going there for a month." "Sure" I said and we took my bags straight out to the plane and I joined the preflight while my sponser had the SDO stamp my orders checking me in and issue me new travel orders.
The Changing of the Bull was a big deal in that squadron requiring appropriate ceremony, food and alcoholic beverages. All on the outgoing Bull's dime. Come 1900 at the BOQ bar, the Bull had everyone assembled ready to turn over when....no me. I'm half way to Adak. I'm told everyone enjoyed her food & booze while she pouted.
So a month later my crew heads back to Misawa arriving at midnight. The next morning I run into The Bull as I am heading to Admin. She is ecstatic. "You're back!"..."Uh, yeah"...."Great! See you tonight at the turnover!"...."Okay...." (not knowing what the hell she is talking about) . I continue to Admin and do all the check in stuff I never did before going to Adak. That's when the YN1 says "sign here"...congrats you are a LTJG as of 2 days ago. Awesome!
1900 rolls around and we all head to the BOQ bar for an AOM (I still don't know about the whole Bull turnover thing). The Bull stands up and kicks off the festivites....
Bull: "Welcome everyone, tonight we ordain a new Bull!"
CO: "We do?"
Bull: "Yes Sir! ENS XXXX is 6 months senior to me and he's finally back from Adak to assume his rightful place!"
CO: "ENS XXXX, didn't I just sign papers making you a JG?"
Me: "Yes Sir, I got them just this morning Sir"
Bull: "FUCK, SHIT"
CO: "Hey guess what everyone? The Bull brought us some food and booze!"
Edit: I forgot to mention that, like MasterBates, she ended up having LTJG delayed for a few months while waiting for another ENS to check in.
