Moving Spoons' room in toto on the night of the 230 Sqn Inaugral Dining-in Night to the balcony over the Officers' Mess entrance whilst he dined (although 230 Sqn did get us back with a kidnapping later that night - can't remember who went for a ride down the stairs in a triwall box though?)
Painting a huge Swift in Red paint of the 230 Sqn Portakabin Roof after Happy Hour one night, the results are still visible on Google to this day. Froze our Boll*cks off, got covered in red paint and almost died doing a drunken traverse of the roof but it was worth it.
Getting blind (almost literally) following a session in the bar making Harvey Wallbangers with some pocheen following some work with the RUC. I had to self auth the next morning as the DA (Adders I think) was still comatose in his pit He didn't surface until 1600 and was very ill for about a week.
FLANGE and CLANG to counter the FOLA
