Salute Your Shorts - Season 1 Episode 7 -

Sponge uses the camp phone without Ug's permission to call into a radio contest. He wins the first round of the contest and a $100 prize. In order to win the grand prize, $1000, he must stay awake for 24 hours and wait for a phone call from the DJ and answer more questions. In exchange for a cut of the prize money, the others help to keep Sponge awake, sneak him past Ug to the phone, and force him to study for the questions.
