don't yank my chain

Know where that expression came from?

Apparently CAME FROM the coal > miners.

They had no bathrooms down in the coal mine tunnel so
consequently they would put a port-a-potty in one of the coal cars.

These cars are usually on a slant so they would detach The car from the
others and put up a chain to hold the car with the potty so it wouldn't
go flying down the mine.

So when someone would get into the potty they > would say to their co-workers,
" DON'T YANK MY CHAIN".

APPARENTLY THAT WAS THEIR ONLY ENTERTAINMENT to yank that chain and watch their buddy go
flying down the shaft while inside the port-a-potty....Now you know everything....
