I had a colleague who was a deep expert in ICD codes, and he used to regale us with funny ones. If I remember correctly, there's one about being wounded by shrapnel from a space ship.
This was the closest I found.
"Spacecraft explosion injuring occupant, initial encounter"
Well, somewhere along the way I came across an item in the tables of things that hadn’t quite fit into their existing neat tariff categories: “bicycle with seven wheels and ten seats” (or perhaps it was ten wheels and seven seats); added in 1993, I think. The really funny thing with that is that the bike shop owner I subsequently bought the trike from was fairly confident he knew the vehicle in question. A slow vehicle, he opined, not very well-made.
Kind of almost sounds like a conference bike but the numbers are bit off.
