Conan O'Brien spent this past weekend hosting something a little different than his normal late night show -- the funny man took over the MTV Movie Awards, where he still managed to put his own spin on the typically tween-heavy outing (do tweens even know who Conan O'Brien is? They do now!).

But, getting ready for the gig wasn't exactly easy -- it's not as if O'Brien frittered away pre-show jitters by hanging out with Zac Efron and dancing to the 'Divergent' soundtrack, because he had something else he needed to work on: getting his hair together. Ever wonder who inspired Christian Bale's hair-don't in 'American Hustle'? (And, no, don't say "the guy the part was based on.") Turns out, it was Conan himself!
