What is a 'Bank run'?
I love it in mary poppins when michael banks causes a bank run because he wants money to feed the birds, tuppence a bag.
"Men think in herds, go mad in herds, but recover their senses one by one." -- Charles Mackay
A bank run is where a bunch of low IQ dumb fucks who think banks put their money inside a large vault for safe keeping demand the bank give them their money back only to find out the money isn't actually there.
I am not surprised an uneducated dolt like you has to ask a question like that.
One of my favorite movies by the way.
I like this saying; it describes the current hysteria.
