Rebuttal's Wisdom

Everyone's had that time in their life when what someone says something in response to another person, and it becomes an, "Ouch..." To me, those times can be pretty annoying, but they can also be insightful. This thread is dedicated to those spunky, jocular, devilish, and gut-wrenching remarks that appear more often than we grant them time to bloom. Sometimes they may wilt in sunlight, other times they become the pathway out of darkness.

They can be quoted from any type of media: advertisements, newspapers, video games, novels, stand-up comedies, movies, impromptu speeches, wherever it came from, you can put it here. Please, I must ask people to write down the source. I don't mind if you quote yourself; this is not a thread reserved for the rebuttals of famous people, I suppose Socrates being one.

I'll just do the most obvious, lazy, over-used, cliche response possible: "Your Mom."

Quite honestly, whoever started that has become famous in their own rite.
