第 4 季，第 4 集: While continuing to work under the watchful eye of Jimmy's efficiency expert, the WYNX staff makes it clear that they miss having Matthew around. Ignoring their requests to hire him back, Andrea alerts everyone to a test she'll be giving. But after Joe steals a copy and Dave discovers that it's for a lie detector, Lisa insists that Andrea cannot force anyone to take it. Meanwhile, when Jimmy's memoir becomes a big hit in Japan, he orders Dave to attend his reading at a local book store. Meeting at a nearby restaurant in order to coordinate what they are going to tell Andrea, the staff is surprised to find Matthew pretending to be their waiter. While lunch isn't forthcoming for anyone but Bill, Dave is stunned to learn that Lisa has several serious arrests on her record. As a result, he insists that everyone keep Andrea in the dark about Lisa's criminal past. And while Beth turns to an herbal remedy guaranteed to slow her metabolism and fool the test, Joe's efforts to redirect the polygraph's electrical current works a little too well. Much to Lisa's surprise, she finds Andrea isn't going to give her the same exam she's administered to everyone else. However, when she cannot keep from blurting out her own secrets, Lisa learns that Andrea has a criminal past, too. Meanwhile, both Dave and Jimmy find that translating his book back into English from Japanese has resulted in a very fractured, memoir. So after Jimmy's reading in New York leaves most of his audience confused, he and Dave head for dinner in Japan where he's a hero.
