What's the worst thing you ever spilled on your computer keyboard?

I knocked over a bottle of cranapple juice on my work computer. The admin scolded me, took it away from me, and sent it to be cleaned. That’s when she found out about all the Doritos crumbs down between the keys (old computer, spaces between the keys). She made sure I didn’t want to get in trouble with her again.

The time I splashed some hot chocolate, though, nobody caught me and I got away with it.

What kind of folly did you commit?
