Klaus, our old flying club mechanic "Benno" had a perfect solution for talkative pilots standing next to him, talking "at" him while he was caught up to his elbows in oil and fuel and dirt... One owned a luxury dress store and his dresses were always exquisite, bright and very expensive.
He began putting an old Volkswagen hubcap next to the front wheel and filled it half with old engine oil and half with avgas.
When said pilot was standing next to him in a white suit and talked at him about his various flying adventures, Benno somehow managed to slide the hubcap right smack behind his right leg.
Mr. Superpilot was not seen in this hangar EVER again. Suitpants, shoes, socks, everything including his white jacket was stained from the mixture, when he took a step back.
Benno was a WWII pilot with metal shreds and pieces on some grenade still encapsuled in his body, very close to his spinal cord, lungs and arteries. The risk of one of these pieces moving cost him his ability to fly, so we youngsters took him out to fly everytime we could.
He could still fly like the devil, 50 years after the war and everyone (except for superpilots) loved him dearly until he passed away.
53 is nothing. Scientific research suggests that most people don't start smelling funny until at least 54.
