went to college with a guy who really was brilliant in the lab, but... while I was out scrapping and cussing , he came out with a pan of hot water and poured it on his windshield before I could warn him. I recall saying " Idiot, you cracked your windshield." He replied " Idiot, the cracking noise is the ice coming off, anyone who is anyone knows that, basic thermodynamics."
So.. when he got in, to start the car, saw the damage and I was laughing my ass off and as I drove away and made some rude comments about physical chemists..
