I have taken a look at this website's idiom list, I think there's one thing missing - examples.

I guess it's too much work for the webmasters and editors to add examples for all idioms in the list, so I'll just ask about the idioms I have hard time understanding.


About face - can you give me some examples? it just sounds so weird to me that I don't know where and how to put this into use, even though I get the meaning of it.

Ambulance chaser - I don't like how it sounds. Does it have cynical tone?

As cool as a cucumber - where does this come from? I don't think there's any attribute about cucumber you can say cool about. I may even have taken it as an insult if someone told me I'm as cool as a cucumber.

Banana republic - can Cuba fall into this catagory?

sixty-four-thousand-dollar-question: is this expression still alive and active? or is this almost obsolete? And why just $64,000 when you can put a few more zeros behind? any story behind it?

Thank you very much!
