I try to avoid embedding too many videos here, but this happened a few hours ago.
Or you can watch it here instead.
That is a commercial for Cheer detergent featuring Dick Gautier as Not!Spock. The date I came across for it was 1969. I have no idea if that's accurate, but it must be in the ballpark. After all, I can't see such a blatant rip-off flying after the mid-1970s.
I am actually really taken by the transporter FX used in this, and by Gautier's channeling of Leonard Nimoy. Too bad he (apparently) was never called on to play a Vulcan for real!
