I thought I'd share this one.
My father was an old school Engineer and worked one everything from
aircraft to underground mines, but did not understand electronics.
At one place he worked he setup a unique way to run multiple
audio sources to each of the other engineers desk / drafting tables.
He had about 3 or 4 radios each tuned to a different station and then ran
wires along the wall to each guys desk where each had a set of headphones
with alligator clips on them. They would clip onto the wires of the source
they wanted to listen to. So those wanting talk radio would clip onto one set,
classical music another, etc. I get a chuckle at his solution but it did work.

Quite near my childhood home one set of RR tracks crossed over another. There was a part of the bridge where you could climb down and reach the telephone pole's wires of the bottom road.
I used to aligator-clip on a single antique headphone element to a certain set (the one that transposed wire position every few poles making a miles long twisted pair) and could talk to the yard operators in distant towns. I'd call their yard by name and they'd answer - it amazed / amused my friends. Some amplifiers they must've had on that phone line!
