I thought it was bad porno or an old episode of CHIPS!
Well, I knew it wasn't from CHiPs. Oddly enough, I've watched every episode and every season of CHiPs. They started re-running for two hours in a row while I was an undergraduate very early in the morning; I watched them with my coffee daily. The episodes with Jon's replacement sucked.
I enjoy the detail in this clip. The high-speed killing blow is delivered with a real wobbly looking toss (looks like one of my sh1tty putts).
