My personal favourites have to be:
3) Use the Time Machine to Cheat
…John will say “Well, Terminator, I’ll just make sure my future self sends someone back in time to set up a bucket to drop on your head!” Then the Terminator has a bucket dropped on it’s head with the words “Wild Stallyns Rule” written on it, and oh, isn’t Skynet embarrassed! Excellent!
And of course:
2) Have the Terminators Step in Front of his Lighting
John Connor hates that shit.
