Im in quite a pickle please help!?

Ok so lately my mom and grandma have been supper annoying! Basically all they do is watch Oprah all day and make me do all there chores! like rubbing there feet, cooking them meals, doing there laundry, and picking up my grandmas dogs poop! also my grandma likes to watch inappropriate shows so she makes me go to bed at 9! and im 20 years old! so as a way to get back at them i decided to throw the tv down the stairs while they were eating breakfast(its the only time of day there not watching tv) Now we have no tvs and because it was brand new and very expensive we wont be getting a new one for a while. But instead of laughing about my prank they are all mad for no reason! Now they want me get a job to pay for a new tv,like ive got nothing better to do. How do i get out of this!???? Any advice?Like i said im in quite a pickle
