Video Vault -- Knockout (NBC, 1977)

This could also go up on my daytime game shows thread on the TVMSC board, but I feel a need to bump my journal down a notch so for now it will go here:
To close out 2012 (and to my eyes good riddance to it, that's a long story), here's an episode of the short-lived NBC game show Knockout, hosted by Arte Johnson, which ran from October 1977 to April 1978.  Most of the elements from this, save the cash aspect, would eventually be found in the BBC game show Odd One Out a few years later.
You might remember Arte Johnson from Rowan and Martin's Laugh-In; he's the guy I remember most for saying "Verrry Iiinteresting" (if I'm not mistaken).  And in my opinion, he does a decent job keeping things moving here with a simple game that's essentially about sniffing out what doesn't belong in a list of four items.
This episode is missing the intro and part of the end credits but otherwise is essentially complete.  One thing to note is that there is a reason contestants on this show were allowed to lose two games before they were done; games could end very quickly and you will see an example of that here.
