Back in May, we posted a video of Bill Hader talking to Howard Stern about how big of a diva Justin Bieber was during his Saturday Night Live hosting appearance this past season. I remember watching the show and thinking, "damn, all the cast members sure do seem uncomfortable doing anything funny with this kid." I wasn't exactly wrong. Hader called this sketch from the show's dress rehersal, "the greatest trainwreck ever" thanks to an audience of tween girls who didn't get the humor and a wall almost falling on Biebs.
If you're curious about the anatomy of a disasterous SNL sketch, stick around for the commentary by Hader and writers Rob Klein and John Solomon.
