Julianna Margulies & Jimmy Fallon School The Rest Of Late Night On What's Funny (Hint: It's Them)!

Good Wife? More like good at everything!
Julianna Margulies stopped by The Tonight Show to rub elbows with Jimmy Fallon and promote her Emmy-winning show.
But mostly she promoted laughter as the Vice Principal of Saugerties High School!
Ch-ch-check out the video (above) to see the musical duo do HIGHlariously terrible parodies of Taylor Swift, Beyoncé, Iggy Azalea, and more!
