Check out HISHEdotcom's hilarious take on how Iron Man 3 should have ended; From the same folks who brought you:
Jurassic park: How It Should Have Ended,
Return Of The Jedi: How It Should Have Ended,
Super Cafe - The Super Social Network,
Super Cafe - Bat Phone,
The Dark Knight Rises: How It Should Have Ended, and
Indiana Jones and the Last Crusade - How It Should Have Ended.
Don't miss the special cameos by Superman, Batman and The Avengers. LOL.
