For this Sunday, just some old mathy humor:
A philosopher wishes to measure the height of a certain flag pole. All he has to do so is a measuring tape, and though he tries and tries he is unable to slide the tape up the full length of the pole. Eventually, an engineer comes by and sees the philosopher struggling. He says, "allow me," at which point he pulls the pole out of its hole in the ground, lays it flat on the ground, and easily measures it.
“Your pole is 5.5 meters long," he announces.“But,” says the philosopher, “I wanted the height, not the length!”
