It's raining cats and dogs--and other beastly expressions

the long version

Do you have an "eagle-eye" for a bargain? Have you ever been "hounded" by a "loan-shark" or hustled by a "pool-shark"? Have you been the victim of a "stool-pigeon" or a "rat", or the "scapegoat" for some "foxy" character's misdeeds? Expressions like these lend color and character to our everyday conversation. Many of them are so familiar that we rarely pause to wonder how or when they came into use in the language. But their origins are fascinating to discover and fun to share.
