This is a random idea that popped into my head
Hope you enjoy it!

Snape was patroling the dungeons for any signs of mischief.
He heard some strange noises from a room that use to be used for torture.
He opened the door and saw Argus Filch hanging upside down from a pair of shackles.
He said,''So Filch,Just hanging around?''
Argus glared at him and said,''Haha very funny''
''Do I want to know how this happened?''
''Probably not''
''Well, I shall leave you to your business, whatever it may be''
Argus rolled his eyes as he left
He then realised, That bastard forgot to cut me down

Probably not that good, but please tell me what you think
