I saw this on Concealed Nation.
I'm not sure if it was posted already (searched for 'killer clown' and only got a few hits of other things).
The first interesting part is at 1:10...there's a huge guy with two kids and the clown actor got laid out by a right cross. I think he actually got knocked out.
The other one is a guy that was CC'ing at the 2:26 mark. I'm not sure if this one was staged, because I think it's in NYC...CC'ing is rare there (but not unheard of).
