Query: This is the funniest book that's ever been written in the English language

Didn't you hear me the first time?This is the funniest book that's ever been written in the English language.It helps to know that the "Quads" are the perpetrator's quadruplets, but other than that single pause, I laughed my head off. I read the thing on a flight from London the New York, and twice the flight attendant thought I was having an epileptic fit. I could not speak the second time, and I just held up the book, and she seemed to immediately understand.This is the book they killed the Germans with in Month Python.You've been warned.
