Justin Bieber helmed last night's Saturday Night Live, attempting to seduce audience members with roses and weird, often wrong, factoids about the intersection this month between Valentine's Day and Black History Month. “Girl you’re driving me crazy, but did you also know Denzel Washington invented peanut butter?” he says in his opening monologue, which ended with him serenading Whoopi Goldberg. The Canadian singer later appeared to apologize for a certain incident involving marijuana, notes the Hollywood Reporter, while playing a Miley Cyrus fan who hates the Biebs: “I also heard he got busted smoking weed," his character says, "and people make mistakes and he’s really sorry about it and he’s never going to do it again.” Mike Ryan has his SNL scorecard over at Huffington Post.
