Julianna Margulies and Jimmy Fallon are Singing High School Principals on Tonight Show (VIDEO)

Julianna Margulies and Jimmy Fallon played principals of Saugerties High School on The Tonight Show on Tuesday, September 16, 2014.

They parody Taylor Swift, Iggy Azalea, Beyonce and Sam Smith to spice up their morning announcements.

Again, another funny bit from Fallon. Good job Julianna Margulies!

Jimmy Fallon has really spiced up late night since he took over The Tonight Show this year. He's gotten so many celebs to do crazy stuff over the last year and even had a duet with Barbra Streisand this week.
