...when a young penguin type fellow could start a thread like this: https://www.physicsforums.com/showthread.php?t=103616 and almost all of the people here would instantly understand it was humorous. In fact, they would pitch in and add to the humor, extending it and developing it, all with a straight face. No one had to ask "Is this supposed to be a joke?" or try to bring the whole thing to a halt and "correct" the erroneous notions. Everyone got it. I think things are in a sad state around here, humor-wise.
