Yeah...I got busted for laughing while others were being chewed up. Sometimes you just couldn't help it between what the TI would say and the stupid response a recruit would utter.
"Don't be first or last; the fastest or the slowest; the smartest or the dumbest; the tallest or the shortest; the fattest or the thinnest. When you arrive, don't have the shortest hair or the longest. Be in the middle. All the others provide you with cover."
