When The Schemer pulls the switch down, the next scene shows the switch is up.
Schemer: Not even you can stand up to my destroyer monster. (to robot) Seize him and hold him!
Space Ghost: No thanks. (grabs Schemer and throws him at robot) Why don't you try it.
Schemer: That's finally the end of Space Ghost and his friends.
(Space Ghost bursts into The Schemer's control room)
Space Ghost: No, Schemer. This is the beginning of your end.
Space Ghost: A thug like you couldn't think of anything pleasant.
Schemer: Oh but I can, Space Ghost. I can think of how you've thwarted my plans for the last time.
Space Ghost: (barely avoids being hit by ray) Wow! That cruiser's armed with a megaton ray! Can't fool around, I'll have to knock it out in a hurry with my energy force.
