That one happened to a friend of mine in the late 80's.
User, "I think my monitors on fire."
Friend, "What!?"
User, "There's smoke coming out of it!"
Friend, "Have you turned it off yet?"
User, "Are you crazy!? I'm not going near that thing!"
Cue friend running out of the building, up the street to the other building where the user worked in the pathology lab, & into the lab to disconnect the monitor. Turned out that they has spilled a significant quantity of ethanol into it... (or maybe water, not sure any more.)
