Cathy gets ungrounded for destroying her brother's remote control helicopter since it woke her and her parents up.
Dylan: I'm going to play with my remote control helicopter.
(cuts to Cathy sleeping)
Cathy: What's that sound?
Cathy's mom (offscreen): Keep it down, Cathy! TJ is trying to sleep!
Cathy: I know Mom but I can't sleep too! Something is keeping me up! Wait a minute, it's my brother Dylan and his remote control helicopter! That's what's waking me up! I will destroy his helicopter!
(in Dylan's room)
Cathy: Dylan, how dare you wake me up with your helicopter? That's it! I will destroy it!
(Cathy destroyed helicopter)
Dylan: Oh no! Cathy, how dare you destroy my helicopter? That cost me $150! I'm telling!
Cathy's mom: What is it Dylan?
Dylan: Cathy destroyed my helicopter and it cost $150!
Cathy's mom: Well, good!
Cathy's mom: You kept your sister up by using your remote control helicopter and my husband and I as well! That's it! You are grounded until Christmas! Go to bed now!
Dylan: I hate you!
Cathy's mom: Cathy, thank you for destroying your brother's helicopter. You know it kept us up all night. You are now ungrounded.
