Belgian Hole Diggers
Thomas and Maxim were working for Provinciale Ontwikkelingsmaatschappij Antwerpen (they take care of the roads in Antwerp).
One would dig a hole and the other would follow behind and fill the hole in.
They worked up one side of the street, then down the other, then moved on to the next street, working furiously all day without rest, one Belgian digging a hole, the other Belgian filling it in again.
Ali was driving by with his Tesla going to a tier 2 meeting. Amazed at the obvious stupidity he asked Thomas.
"I am sure you feel great putting down all this effort, but I don't get it... Why do you dig a hole, only to have your partner follow behind and fill it up again?"
Thomas wiped his forehead brow and sighed, "Well, I suppose it probably looks odd because we're normally a three-person team. But today the other guy who plants the trees called in sick."
