The Suite Life of Zack & Cody (2005)

S03E02 Summer of Our Discontent

Cody is on the hunt for a summer job and spots a "help wanted" sign at the nearby mini-mart. The owner agrees to hire him, but only if Cody can arrange a date with London for him. Meanwhile, Zack learns he's the top student in his summer-school class, but the other kids mock him for it.
