Probably been said before, but Iron Man, Mark II would be good as well.
I still say Iron Man 2: Electric Boogaloo is pure gold.
Iron Man 2: The Secret of the Booze
Iron Man 2: Scarlett's Web
Iron Man 2 1/2: The Smell of Beer
Iron Man 2: Raiders of the Lost Stark
You realize "Electric Boogaloo" is brought up as a joke title for every single sequel ever, right? It comes from the movie Breakin' 2: Electric Boogaloo. It was quite funny for a while, but it's massively played out.
Iron Man II: Shock to the Heart ?
