Terminator 2: Judgement Day (1991)
A cyborg, identical to the one who failed to kill Sarah Connor, must now protect her nine-year-old son, John, from a more advanced cyborg, made out of liquid metal.
I would like to see this one riffed, as well! Hell, I think the first one should be riffed! Loved the Terminator 3 riff they did. Do 'em all! Weeeee!
