One of my friends at university (at a top level institution) found himself holding a live plug a on Jesus lead left behind by
a
previous graduate student. The burns from that were horrific. Once attached you can't let go or move and burning human flesh
doesn't smell good. He was probably only on for 30s before someone realised and disconnected him.

What's a "Jesus lead"? I tried to google, but what I find are songs.

A mains cable with a plug on each end. In this case plugged into a 4 way extension block under a rack full of electronics in a

So named because it gets you closer to God.

Google seems singularly unhelpful on this one...

I once went into radio shack in the US and asked for an extension mains lead.
I got a blank look, so I pointed to what I wanted and learned that I should have said power cord.

It was common, in the days of tube-based TV sets, to salvage the power
cord ("cheater") from an old set. The cord on the set was affixed to the
back cover to provide an interlock so you couldn't operate the set with
the cover off. The "cheater" eliminated that restriction -- at a bit
of risk to the user.

I don't think the back of our tube-based TV was ever on.
While it was under warranty, service people seemed to arrive monthly.
When it was out of warranty I learned a lot about the practical side of electronics.
Eventually it ran reasonably reliably until the picture tube gave up so my father and myself replaced the A66-140X
https://www.google.com/search?q=beovision+3400+pdfI don't think the UK ever had any tube only colour TVs, they were all hybrids (tubes for high power / high voltage) and
semiconductors.
In the above case all discrete except for one integrated circuit (line oscillator).
