Query: most useful Italian phrase book... ever!

This is a book that you definately need to see (really, see) to appreciate it. It's got all kinds of useful and not-so-useful phrases, such as "I'll break your knees!," "I'll blind you!," and "You're beautiful!" It shows you the proper gesture, a phrase to go along with it, and even how to correctly pronounce it. Get this book, even if you have no need to learn any Italian phrases. It's hilarious, and definately worth the money.
