'Uckers' was definitely one of the traditions the RAF inherited from the Senior Service!
We let them keep rum, bum and the cat o' nine tails though - fortunately!
The last time I recall playing Uckers was during a ME refresher course at Arthur Scargill International when the Wg Cdr on the course and I decided to take on a team from the AFTS students. It went on for most of the morning - until the miserable old farts who instructed on the Wetdream moaned about "Students wasting their time playing games when they should be working". The Wg Cdr (excellent bloke!) gave them a sound debrief concerning the value Uckers played in the real Air Force for team building. But agreed that we'd played enough that day.
I hated every minute in the god-forsaken Wetdream!
