Uncle Harry is an episode of the Alvin and the Chipmunks series.
A charlatan chipmunk named Harry tells Alvin, Simon, and Theodore that he is their long lost uncle. The Chipmunks do concerts and stuns in order to get the money that Uncle Harry says will help them visit their mother, though they must leave Dave in order to perform. The strenuous pace of these concerts are taking a toll on the Chipmunk's heath, and the true reason for the concerts is for Harry to make money to retire his debt to Luke, a circus strongman who is getting impatient with Harry's excuses not to pay. After the boys overhear Harry talking to Luke claiming he was a fake, they devise a plan to get their money. The plan goes sideways, but they improvise by scaring Harry. As The Chipmunks head back home, glad to see Dave again, Harry travels to Alaska, thinking that's where the money is.
