It's a remote.. not the TV.. they cost like $20 to get a new one just apologize and tell them what happened.
Worst possible suggestion, don't listen to him OP. Your parents are gonna beat you upside the head(???) for breaking the TV remote.
Well yeah, they'll beat you upside the head. But there's nothing you can do.
He can tell lies or pin the blame on his sister like a responsible, wholesome human being. Even if his parents find out they'll be too proud of him to beat him upside the head, it's absolutely a win/win scenario.
Smear human feces on the wall right inside from which ever door they are going to enter through. The stuff on the wall will distract them from the tv remote.
What if OP put on a remote costume? I think that would trick his parents into thinking everything is alright until he finds a suitable replacement
