Freaking ULTRON of all things!!!!!
(Evil robot Ultron to Iron Man): "Why, Anthony....who DO you think you're TALKING to?"
(Tony Stark as Iron Man): "I'm not afraida you....and I'm NOT gonna suck certain bodily organs for you, either!".
(Ultron): "Not even for some wonderful CRACK, Tony?" (waves lit crack pipe in front of Iron Man's mask...)
(Tony) "Uhhh...well, maybe just ONCE."
(Ultron) "Yeahhh, that's it...just once...."
Movie ends thusly:
<Rhodey is driving Tony & Pepper into the desert in a classic convertible to a fancy-ass rehab clinic....Tony starts to turn pale & sweaty & falls into the seat....Rhodey stops the car, as he and Pepper cry over Tony's corpse.....the screen flashes to the saddened faces of Captain America, Thor, Dr. Banner, and Nick Fury as they hear the news on TV...Billionaire Tony Stark, known also as the superhero Iron Man...is dead...for real, this time, not like that one time when the Mandarin had those helicopters blow up his Malibu home...>
(Music plays, with more Iron Man/Avengers flashbacks)....Time, time, time.....see what's become of meeee.....)
