WATCH: Kate McKinnon's Ruth Bader Ginsburg Impersonation Dominates SNL's Weekend Update

Do you want to know the real reason 81-year-old Supreme Court Justice Ruth Bader Ginsburg fell asleep during President Obama's State of the Union Address? How about her workout routine? Perhaps you just wanted to be reminded how hysterical Kate McKinnon is on SNL? Look no further, because this week on Kate arrived at the Weekend Update desk as Ruth Bader Ginsburg, and she had lots to say about her fellow Supreme Court members, Bruno Mars, and the state of Alabama. She also busted out some sick moves in her courtly attire, and we busted out in uncontrollable laughter. Verdict is in; Kate McKinnon totally rocks.
