My dad likes to tell a story about a time he was riding on a subway car next to a shaggy looking guy with a laptop. My dad looked over and asked “oh, is that Linux?” and the guy replied “it’s GNU /Linux, actually” in a really snarky way. My dad snorted and said “who are you, Richard Stallman?” and he said “yes”.
