Last weekend, Jack Black hosted SNL to promote the Super Mario Galaxy Movie (which just premiered last week). SNL fans enjoyed the show, some saying that it was one of the best episodes of the season. Jack White was the musical guest.
During a sketch titled "Words to Live By," a song sketch about forgetting important information, Jack White had--what was supposed to be a triumphant guitar solo. However, White flubs it purposefully to humorous results.
Silly stuff! Watch the sketch! SNL! Yes! Jack White also performed some of his own music later in the show!
