Patrick joining along. Eventually, Mr. Krabs stops their gibberish explanations and tells them to simply explain the problem. Once they do, Mr. Krabs angrily removes them from the restaurant and prepares a punishment. SpongeBob and Patrick make a vow to stop using the bad word, be good citizens like Mr. Krabs. As Mr. Krabs is about to tell them to paint the restaurant as punishment, he hits his foot on a rock, prompting him to yell out all thirteen bad words in pain.
