My dad's 71 and semi-retired now. He told us a story when him & a friend worked for a contractor running bulldozers to drain a swamp. Seems they spent most of their day pulling each other out of the mud when one or the other got stuck. So the boss shows up and want to know why they didn't finished yet. He figures to give them a lesson in 'dozer driving, hops on one of the machines, and in one pass gets it planted! Dad said the guy never said a word, just got off the machine, slogged out through the mud, jumped in his pickup and left.
He said him & his friend could barely wait 'till the boss left to break out laughing.
