Quote from The Big Bang Theory 10x09 │ Sheldon Cooper: I tried to let go of anger and threw a rock into my foot! Leonard Hofstadter: Then he got more angry and kicked the rock with his other foot. Penny Hofstadter: Wha–? And what happened to you? Leonard Hofstadter: Oh, I laughed so hard, I burst a blood vessel in my nose. It’s fine.
