I'm in! I practice the Zimmerman all the time. But I added sand bag arms and legs to the sack of stupid and let my children shake the piss out of it to simulate a real fight. If you don't practice for real, don't practice. There's nothing like slinging a few Hydro shock's around within inches of your 4 year old.
Oh and by the way. Carl Grimes at 10 years old don't have chit on my 4 year old. And my 1 year old scares both of us.
