There's no better form of therapy than a well-timed insult, and we got just that on last night's series finale of 30 Rock. Not even Shakespeare himself, the king of biting insults, could deny that the hour-long episode had its ample share of below-the-belt disses. Check out this collection of the episode's best zingers, and high-five a million angels each time you get a chance to use one today. We salute you, 30 Rock writers, for finally finding a way to use "chin slit" in a sentence.
