Think of the opportunities to purge one's aggression!
Two o'clock in the morning...why I feel the need to play In-a-gad a-da-vida at max volume, with the twin 500 watt Kenwoods pointed directly at (if not touching) the door of the squatter pieces of shit.
Passing one of them in the hallway...an earshattering fog horn, just to make sure they mind the drop of spilled liquid on the floor.
I can go and on, but I damned well assure you they'd be the hell out of my home pretty quickly.
Then take me to court!
Can you say jury nullification?
Although in Californicate, it's doubtful you'd find one conservative with balls to sit on the jury.
Honestly, if you really want them to leave, they will leave. Taze them, kick the in the head and then throw them out. When the cops show up, you have the address and they don’t.
