Mine is when Arnie were smacked up by Christine's stepmother...
Hehehehehehehe.....I laughed when imagined the almighty Terminator who can't be beaten easily in Terminator series is nothing for an old grandma...
He was striken by a piano, same with T2's scene where he is crushed by T1000 brutally...^^ of course not with a piano
When Arnie tells Satan "You're a choir boy compared to me, A CHOIR BOY!!!!"...Okay, how can you be more "bad" than The Devil, who epitomizes all evil? Not too mention there is literally nothing we hear or see from his character that suggests he's that much of a bad ass, clearly no Matrix or Dutch or T-800, his Mr. Freeze is considerably a more tough customer.
Satan dealing with the punk kid with the shirt, such a pointless and stupid addition but amusing nonetheless.
And yes, Arnie getting smacked around by the stepmother was indeed hilarious, did they seriously think people wouldn't find that part unintentionally funny in any sort of fashioned?
