Justin Bieber got a chance to test his improv chops last night on 'Saturday Night Live,' only to be knocked clean out of character by Taran Killam's hyperactive antics.

In this sketch about an older brother hazing his sister's new boyfriend, Killam pulled out all the stops. He even aggressively manhandled the young pop star, apparently trying to absorb his magical essence. Bieber was unable to hide his laughter, but pulled it together eventually. To be honest, I doubt any of us would have done much better under such an onslaught!
