The thread title reminded me of a story about Tony Iommi of Black Sabbath setting drummer Bill Ward's socks on fire, not exactly a prank but probably literal-mindeness gone too far as a result of Mr. Ward inquiring of Iommi's intent as expressed prior.
Even that was a one-time incident, it mystifies me how the employee in this case could have a known history of engaging in malicious horseplay, especially in regard to the misuse of carcinogenic chemicals
