Derek's mom-Catherine


Derek punches Kumi all because she touched his plane after he told her not to touch it.


Derek: I told you not to touch it!

Kumi: You built it all wrong! Didn't you read the directions? It didn't fly for one second! It's not my fault if you made a plane that can't fly!

Derek: I told you not... to... touch it!

(Derek punches Kumi)

Kumi: Waaaaaaaaaaaaaaaaaaaaa!

Derek's mom (offscreen): Derek Alan Crystal! Get over here right now!

Derek: Uh-oh! Middle name!
