For years I’ve heard the phrase bandied around:

How do you like them apples?

Now I finally have a source. A little smart googling brought me to this “entry in the Urban Dictionary site”:http://www.urbandictionary.com/define.php?term=them+apples and it turns out it’s a line from Howard Hawks’ Rio Bravo.

In the movie Stumpy, played by Walter Brennan, tosses a grenade and shouts How do ya like them apples?
