Belling The Cat

BELLING THE CAT: One of the many fables
attributed to the Greek storyteller Aesop
concerns a meeting of mice. They are concerned
about a cat. One mouse has an ingenious idea:
tie a bell around the cat's neck so they can hear the cat
when it is coming. A wonderful idea but with a problem...
which mouse is going to put the bell
on the cat? The job would be suicide.
No one volunteered. The phrase belling the cat
is still in use today. It refers to any idea
that looks good on paper but is useless
in the real world.
