Tolerate ignorance? Really? So not necessary. This laugh-out-loud dictionary is the perfect lesson in snarkiness.  Why suffer the tiny minds of the plebian rabble with whom you come in daily contact, reasons James Napoli, executive vice president of the National Sarcasm Society. So, with The Official Dictionary of Sarcasm, he provides an A-Z guide to turn to whenever you need to set someone straight. From advertisements to e-mail, materialism to remote controls, there's a witty answer for every situation. "You have been waiting patiently for a dictionary like this to come along. And now it is here," recognizes Napoli. "Not that you give a crap."
