Conservation of Humor

I love witty graffiti.
Pulling an all-nighter in college with some fellow students, I needed to take a bathroom break around 3am. We were studying in Ryerson, former location of the Physics department, but now home to Computer Science. The restrooms typically used during the day were locked, so I headed up to the ones on the third floor. (Known to be unlocked for faculty working unpredictable schedules.)
Walking in, I flipped on the lights, and did my business. After washing my hands, I walked over to switch to flip the lights off again. Along side was a common, official sign saying “Please turns lights off to conserve energy.”
Only a former physics vandal had crossed it out with a big, black X and scrawled underneath, “Energy is always conserved.”
It might have been the stress of finals, but damn, was seeing that funny.
