Cody goes to math camp in the “Cody Goes to Camp” episode of Suite Life of Zack and Cody (Season 1, Episode 10).
While Zack thinks he’s going to have a blast with his brother out of his hair, he discovers that things aren’t quite as fun around the hotel without his nerdy twin.
Cody meanwhile is having a blast connecting with like-minded math nerds at Camp Knock-A-Number, but convinced that Cody is having a terrible time without him, Zack hatches a plan to go rescue his brother. Only when he arrives, he discovers he doesn’t need or want to be rescued.
The scenes at Camp Knock-A-Number are in a sound studio set that looks more like a backyard than a summer camp, but what do you expect from a Disney Channel show set in a hotel?
