During the last class I taught at Purdue, I went to the whiteboard at the front of the lab and wrote down some notes. Then I tried to erase them—no go. Some witty person had put a big, black El Marko permanent marker in the tray of the whiteboard in the lab. Very funny. The maintenance crew for the building had some sort of super-special spray that took it off, but here's a simpler solution from LifeHacker that involves a regular dry erase marker and an eraser.
