From the opening monologuewhat’s funny, what’s dangerous, what’s untouchableto the best vs. worst guests (think Billy Crystal and Martin Short vs. Kristen Stewart and John Edwards), Macks covers the landscape of late-night comedy and punctuates the narrative with hysterical personal anecdotes and draws from more than half a million of his own jokes written over the span of twenty years. With an insider’s expertise and a laugh-out-loud voice on every page, Macks explains how late-night TV redefines the news and events of any given day, reshapes public opinion, and even creates our national zeitgeist.
