Inside joke we were in stitches this arvo at the esky bar. Joking about ppl having really strange hobbies such as trainspotting, then it went down hill to ULD spotting (A guy in the UK does it aparently), and went to everything from Serial numbers of the rivets on the fuselage, to serial numbers of seals in the fuel bowsers you get at the local Shell servo... funny joke there too
