interrupt the blood suppy to the brain by any means necessary

call them on their mind games +5

There are several chemicals, such as the one with the street name "knock out drops," but these are illegal. The physical way (what I consider the safest and least damaging) is a firm punch to the solar plexus, which is below the breastbone behind the stomach, where we call the "pit of the stomach." When I was a kid, a bully dropped me with a punch there. I got dizzy and passed out. When I came to, I was ok. But this is also illegal, it's called "batery!"

Choke them till they pass out...If you want to kill them, just continue choking!

Show up at my door wearing that little see through thingy with the apron.

A sledge hammer should do it.
