I drew this on the bottom of a material science homework. They gave me a 30/100 in a big marker and recommended I drop their course if I wasn't serious about it. I later discovered that, of all the disciplines at CMU, material science is the only one with no cartoons at all in their hallway. That's odd. I always found it to be an inherently funny discipline. It involves smashing things, blowing things up, and so forth, usually by applying greatly excessive force.
