Casey trips at school on the staircase (and takes it out on innocent bystanders) after Derek insults her. Derek can't stop laughing as he and his best friend, Sam, look on. Derek nicknames her "Klutzilla", a name that quickly spreads throughout the school. The whole school is "watching out" for Klutzilla and she blames it all on Derek. A second incident happens when Derek insults her again and she falls into Marti's box in front of Sam. Soon, Derek connects the two incidents to Sam and accuses Casey of secretly crushing on him.
