Did you hear what happened at [insert aerodrome at which Groom operates here] last week? The conversation between the control tower and the runway inspection vehicle went like this:
Tower: Car 1 this is Tower. There's a nude pilot sleeping on the threshold of runway 34. Please get him out of the manoeuvring area.
Car 1: Tower this is Car 1. Wilco. By the way, how do you know he's a pilot from up there, especially when he's nude?
Tower: He's got a large watch and a small penis.
(At this point, grab Groom's wrist and show everyone the large watch he's wearing.)
