Comedian Maya Rudolph, who is known for her hilarious impressions of stars like Beyoncé and Oprah on "Saturday Night Live," spoke during the Tulane University graduation in New Orleans on Saturday morning and she did not let the crowd down.

While singing "The Star Spangled Banner," she asked the graduates to rise as she gifted the stadium with her over exaggerated singing, just like she has in her previous Beyoncé impressions. The national anthem quickly transitioned into Beyonce's hit songs "Single Ladies" and "Drunk in Love."

"Look at all these beautiful faces...and iPhones," Rudolph said before she began her official speech. "Families and friends of graduates, mothers, fathers, brothers, brothers from other mothers, sisters, roommates, grandmas and grandpas, meemaws and papaws...and people who met on Tinder this morning. I thank you for having me here to join you on this special day in this incredible city. I stand here humbled, gracious and completely naked under this robe."

Rudolph continued her comical attitude through most of the commencement, joking about how she wrote her speech earlier that morning from her hotel room, with plenty of naps and some episodes of "Game of Thrones" in between.

Oprah Winfrey was even channeled during the speech when Rudolph jokingly exclaimed in her best Oprah voice, "And today, class of 2015, look under your seats because you are all leaving here with a college diploma! You get a diploma, and you get a diploma, and you get a diploma! We're all getting diplomas!"

According to CBS, Rudolph even decided to embarrass her younger cousin, Sabrina Rudolph, who was in the crowd among the graduating students of the class of 2015 by giving her a shout out and asking her to stand up and wave.
