S5, E11: After Beth persuades the building supervisor to let all the tenants paint corporate murals in the lobby, Dave gives her the day off to finish the one for WNYX. As Beth enlists Joe to help, Jimmy arrives at work with his new personal security consultant, Jack Frost, who Max immediately recognizes as the imposter who once took out his appendix in an emergency operation. Meanwhile, Lisa is irritated when Matthew starts dressing just like her. Despite Max's warnings, neither Dave nor Jimmy see anything unusual about Jack. As Max sets out to get revenge on his own, Beth and Joe argue over just what the office's mural should look like. However, once they are done, it's left to Dave to defend their work from the building supervisor's angry attack. Meanwhile, in an effort to get Jimmy to listen, Max tells him of the appendectomy Jack performed almost eight years ago and recounts other instances where he pretended to be someone he's not. When questioned by Jimmy, Jack insists that he's a real security consultant -- until a chance to pose as the station's news anchor ultimately proves Max's accusation. As Lisa gets revenge by convincing Matthew to dress like him, Dave prepares to defend Beth and Joe's artwork from being censored. Yet, despite his vigorous defense, he cannot keep the building manager from painting over the mural. And following his own encounter with Jack, Matthew is surprised to find himself at work without any clothes on.
