Plankton: Tell him off, SpongeBob. Assert yourself!
SpongeBob: That’s my ice cream cone!
Plankton: Great! Now let him have it!
SpongeBob: You can have it.
Eel: Say, thanks! [walks off]
Plankton: No! [jumps inside SpongeBob’s mouth] I’ll show ya how! Hey, pencil neck! [Electric Eel turns around] Yeah, you, slither over here! [Electric Eel walks over to SpongeBob] Surrender that ice cream cone or every waking moment for you will become a swarming torrent of pain and misery! [Electric Eel throws ice cream on SpongeBob’s face and runs away crying]
SpongeBob: Hey, that guy was crying!
Plankton: Those were tears of joy! He was happy that you were assertive!
SpongeBob: Yeah!
