David and Goliath comes from the Bible.
D-day was the name used for the day the allies attacked the Germans in France during the Second World War.
Send someone to Coventry- there are various theories: http://www.worldwidewords.org/qa/qa-cov1.htm
Catch 22- The tile of a novel by Joseph Heller, who coined the term and the idea
Why do we still use them? Just because something's old, it doesn't follow that it's out of date- many expressions have very old roots.

I think David vs. Goliath means small vs. big. David represents the small guy and Goliath represents the big guy. Not 100% sure so don't take it seriously.

You're right, David.

Well, if you want to know the full story of David vs. Goliath you can just google it if you don't want to use the Bible for whatever reason. But as far as I know the basic premise is that David represents the little man, (unpopular, weak, or powerless, however) who, with sheer determination and righteousness can take down any opponent. Today, this phrase "David vs. Goliath" is applied to basically anything that fits that description...however loosely is actually fits. (Most corporations or businesses will find it in their self interest to apply terms like David vs. Goliath to themselves whenever possible to give them a better image and make them appear honest, whether they are or not.)

Agree or disagree?
