"half a cup of coffee into a CRT monitor. "
Back in university, I had a CRT monitor that allowed me to crank the refresh rate up over 130 Hz (provided I didn't mind turning it into a portable heater)...that is, until I knocked over a 12-ounce cup of lemon-lime soda that I'd stupidly placed on the desk hutch right above it. The monitor instantly released a massive whoosh of steam, but when I cautiously opened it up an hour or two later, it was completely dry, and the next day worked fine aside from losing the ability to have a refresh rate over 120 Hz.
