I remember some good laughs with the UAS in the 80s. Remember meeting a young Flying Officer who was there with 100 Sqn Canberras. There were 2 fish tanks in the foyer of the mess, one with carp and one with piranha. I seem to recall he thought it would be a good idea to introduce the carp to their 'friends' in the other tank which prompted a couple of us to tie him up and dangle him upside down from a sign post outside the mess. Seemed like a good idea at the time and I think it became a bit of a tradition for him!
