What's the rationale behind characters in 1960s TV shows always using the "ha-cha!"* chop to the back of the neck, whenever they need to knock someone out? Like, would that move actually do anything? Would it actually knock someone out? Was it just so much unlike real violence that it wouldn't get them in trouble?
This has been troubling me for a while.
* Incidentally, whenever someone does that move, or whenever Chris and I predict that someone's going to pull that move, we both yell "HA-CHA!"
