I'll never forget when my boss was showing the girl scouts (literally) our very expensive UPS room. He explained how even if the power goes off we'll switch to batteries then switch over to generator power. See watch, he says - then flicked the switch. Fooomm... our entire office goes dark.

This took down news information for a good chunk of Wellington finance for about half a day. (Fortunately Wellington, NZ is a tiny corner of the finance world).

Hilarious! But I admit I was super glad it was the boss playing chaos monkey, not me.
