Sarah G.D. just sent me an email with that phrase. I had never heard it before, but now that I have, I think it needs to be phrase of the week.
This site says: "How do you like them apples?" means "So there! What do you have to say now? What are you going to do about it? Used ironically since the late 1920s." according to the "Random House Dictionary of Popular Proverbs and Sayings" by Gregory Y. Titelman.
How do you like them apples? Where do you put the emphasis?
