No, but it's been an engineering in joke for as long as I can remember. In 1970 I worked for a company that aspired to be a vertically integrated manufacturer of data entry terminals. Those terminals had keyboards, displays, cassette tape drives, and a power supply all inside a single package. We had a guy who designed the display electronics and there was a high voltage section that drove the CRT. Since we had to assemble and disassemble those early prototypes to do our work we were mindful of the advice which he profered, not to put our lips on the high voltage.
Seemed like good advice, then and now.
