There was this chap taking his first solo parachute jump, from a balloon. The drone chute tangled up with the main chute, so he jetisoned it in a panic and could not get the reserved chute to operate. He looked down to see how far from terra ferma he was, to see a chap zooming up towards him holding a big spanner. The guy shouts down "Hey mate do you know anything about parachutes", and the guy holding the spanner replies "No pal, do you know ought about gas ovens"!
