I remember my $6 million man action figure. It came with a V8 engine block that he would lift/curl with his mechanical right arm (you had to keep pressing the button on his back). They also sold snap-on right arms with more features as well as the usual GI Joe style outfits and weapons sets.
Funny thing -- I first saw the show while growing up in Mexico. Due to international exchange rates and such, I imagine that a dollar figure wouldn't sound so snappy in translation. So in Latin America the show was called... "The Nuclear Man".
Makes you want to watch every week and buy the toys, right?
My sister opened a computer store in Hawaii. She sells C shells down by the seashore.
