This.
Most people can't fathom how bad it sucks to be sitting in your house, minus some valuables, but feeling like you can't even take a piss in your own bathroom without looking behind you twice to make sure no one's robbing the place again.

Kool Ade tidal wave.
Take your trash can fill it with water.
Add 2 packs of Kool Ade ( I like cherry as it is red) or other cheap drink mix does not need to be sweetened.
Lean it against your door.
Knock.
Wait for other occupants to open door - red kool ade all over interior. Lulz will be had.
