In the wake of Mark Wahlberg letting us know that 9/11 wouldn't have went down like it did if he had been there, some readers on Sherdog created this thread to document all the others times when things wouldn't have went down like they did. Mark Wahlberg would have saved us all! Or at least his kids and the rest of the first class cabin. He really is one of histories greatest heroes when you think about it (as long as you're Mark Wahlberg).
