S1E7 The Radio Call-In Contest

Sponge sneaks a call on the camp phone to enter a radio contest without Ug's consent. He triumphs in the first round, earning a $100 reward. To claim the grand prize of $1,000, he needs to stay awake for a full 24 hours, waiting for the DJ's call and answering additional questions. His friends agree to help him stay awake, sneak him to the phone past Ug, and push him to study for the quiz, all in exchange for a share of the winnings.
