Career Day:It is Career Day at school, but Dave feels a tad inferior to the other parents, who seem to have more exciting careers, such as Cheesy's Day, Dirk, being an FBI agent. While watching news reports of a bank robber loose in town, and the police department having trouble catching him, Dave decides to take matters into his own hand to try to track and apprehend the robber himself. Unfortunately, The Chipmunks jump to conclusions and figure Dave to be the bank robber himself, and try to stop him. When they do so, they witness the real robber slipping away, while Dirk takes Dave in for questioning; it is revealed that Dirk is nothing more than the police department's IT guy, and that he was trying for a promotion to impress not only his son, but his colleagues as well. After Dave is cleared of the charges, he decides to let Dirk team up with him when he figures out the next bank the robber plans to hit.
