LORD LOVE A DUCK
An exclamation indicating disbelief and stunned acceptance of the facts.
but the first recorded use in literature is found in "The Wheel of Fortune" by Louis Tracy.
No one appears to know how or why or when the expression "he (or she) is an 'odd duck"' originated. Poor duck, being picked on to represent someone who deviates from the norm in appearance, behaviour or beliefs.
I'm just going to 'duck out' of the meeting early. Originally the term was just, 'duck' with 'out' being added later. Why? To give the duck a little class? Who knows. The expression came to life in the 1800's. No one knows why. Ask a duck.
That's my 'fun with ducks' for the day. Got any more duck sayings or expressions?
