It's from the book "Don Quixote" by Cervantes, summarized, readable and searchable here: http://www.online-literature.com/cervantes/don_quixote/

Don Quixote was a knight who at one point in the book took up the lance to fight "giants" ("tilting" refers to engaging another mounted opponent in combat with lances). It is usually assumed, though not completely clear in the book, that Don Quixote thought that the windmills really were the giants.

The phrase is usually used to mean "attacking an imaginary menace."

Sue you? For what? How much money do you have? ;)

To clarify for folks who are not native English speakers, the word you used is actually meant to represent a slurred pronunciation of "another," and it is spelled "'nother" (with the apostrophe in front to represent the dropped "a").

Terry, in the US the phrase is reserved for the racially disadvantaged, not the techno-nerdy overacheivers like you Asian folk. (Pardon my sarcasm... I do honestly admire individual achievement and I think that envious prejudice is just as bad as prejudice that stems from contempt.)

Um, "anonymous" was me, below there.

Somewhat relevant....

Don't be surprised if you are in Texas and ask for a Coke, and your host asks you, "What kind do you want?" They do not mean for you to choose between Diet Coke, "Classic" Coke, Caffeine-Free Coke, and Coke from Mexico in the little glass bottles. They mean, "What kind of soda pop do you want?"

People in restaurants ask, "What kind of Coke do y'all have?" The response is usually, "Coke, Diet Coke, Dr. Pepper, and Sprite."

I have an idea why some (clueless) Americans would object to mineral water or bottled still water if they ordered "water." Here in the States, if you order "water," they bring you a glass of tap water with ice in it. It is free. If you want bottled water, you specifically ask (and pay) for it.

Here's the breakdown:

"Water" is a glass of ordinary or filtered tap water, with ice in it unless you say "Water, no ice." (You can ask for "still water," but not everyone will be familiar with the phrase.) Lemon slices are often automatically supplied, or you can ask for some lemon if you like it.

"Bottled water" is bottled still water. It may be purified city water, mineral water, or "spring water." Make sure they ALWAYS bring you the bottle (not all restaurants are honest about this).

"Sparkling water" is bottled naturally-carbonated water from a natural source. Again, insist on the bottle if they don't bring it out.

"Soda water," "club soda," and "carbonated water" all refer to artificially carbonated water, in or out of bottles.

Also, be aware that if you order "tea" in the South, you automatically get iced tea. In the Deep South, you get presweetened iced tea ("sweet tea," as opposed to "unsweet tea."). If you want a cup of tea, ask for "hot tea."

Yes! It's two baseball games in a row.

The endurance of the fans is not part of the question, actually. :)

Instead of "kevrob" might I suggest "goody two-shoes?"
