Trivia bit about Charles Bronson. As a teenager, he worked in a coal mine, earning $1 per ton of coal mined. In the process he became extremely muscular, and he learned an unparalleled bar trick.
He would insert his thumb and small finger into a shot glass, and spread them enough to pick the glass up. Then he would spread them further, to break the glass.
You’re quick! That’s the first image that came to my mind after the “Grand Torino” reference.
