Watch Justin Timberlake & Jimmy Fallon Rap 40 Years Of SNL Memories

Tonight's 40th anniversary celebration of Saturday Night Live on NBC opened with a musical tribute to the variety show's most memorable moments, starring former cast member Jimmy Fallon and oft-host Justin Timberlake—who briefly brought back "Dick In A Box." (Uncensored, even, in prime time!) This special is bound to be one long act of autofellatio, but we can at least appreciate the tortured parts.
