My first summer job was in a cabinetry shop. I worked there all three summers throughout high school. My boss was a crusty old shop teacher whose sense of humor and store of aphorisms had stopped evolving on approximately V-E Day.
He could be one mean sonofabitch. In fact, I can't watch Reservoir Dogs without thinking about him because he looked so much like Lawrence Tierney and said things like "My way or the highway" in so similar a way.
But sometimes he would saunter up and tell a joke, deadpan, like that one with the punchline: "No, you idiots. Pie are ROUND." Then he'd allow himself a tiny smirk of satisfaction and walk away.
Stay rational out there today.
