Aptitude is the 65th episode of The Suite Life of Zack & Cody. Zack and Cody take career aptitude tests on the computer. Zack is happy about his results, but Cody is not. Meanwhile, London gets jealous of Maddie when she saves someone's life and gets on television.
The episode starts with Cody taking a career aptitude test when Zack sees him, and he decides to take the test too. The results come in and Cody learns he is going to be a sanitation engineer while Zack becomes a CEO (he mispronounces it as Kee-O). Zack starts reading magazines about the stock markets and is doing math. When they are asleep, Zack dreams he is the CEO of Zack Inc. and is making lots of money (he even has enough to buy Australia) while Cody's dream is about cleaning up Zack's office while he celebrates how he did on Wall Street. Carey comes inside the boy's room and Cody tells Carey that his life is going to be cleaning up after Zack. Carey then tells both of them that the test is not important. Cody then asks if he should believe her over the Life Assessment Corporation. The next day they go to there, and Carey tells the guy in the office that Zack and Cody will be whatever they want to be.
Meanwhile, London comes back from Morocco and is inviting a Moroccan ambassador to dinner at the Tipton. London also arranged for a professional belly dancer to entertain the ambassador, but has to settle for Maddie, since the belly dancer had a stomachache. When the ambassador chokes on one of the kebabs, Maddie does the Heimlich maneuver and saves the ambassador's life. As a result, Maddie is on the cover of magazines and even gets to be on television! London becomes jealous and decides to take back the spotlight by getting Patrick to choke on a kebab and London saving him. But London, after tasting a kebab, chokes on it and Maddie saves her. The next day Maddie learns that some other news has taken the spotlight away from her. Maddie is depressed, until Moseby reminds her that she did a good deed.
