Jimmy Fallon loves to include his celebrity guests in crazy sketches and games. He recently threw balls at Julia Roberts' face, sucked helium out of balloons with Morgan Freeman and rolled around on the floor with Heidi Klum. However, none of the sketches on "The Tonight Show Starring Jimmy Fallon" have been quite as sophisticated—but still silly—as this one.

Fallon dressed up as a medieval page boy and sought some deep, existential guidance from Academy Award-winning actress Helen Mirren, who appeared as a "Mirren, Mirren on the wall" during Monday night's episode. In his spot-on British accent, Fallon summoned Mirren in the magic mirror, obviously playing on the famous phrase from "Snow White."

Think about what you would want to ask Mirren if you were in a room with her. Maybe some of your questions would be "What inspires your stellar performances?" or "Why do you not age?" or "How did you learn to twerk so well?"

Instead, Fallon asked "Mirren, Mirren" such important questions as what's her favorite film ("Sharknado"), her dream job (being a contestant on "America Ninja Warrior") and her thoughts on "50 Shades of Grey" ("Who doesn't love a jolly good spanking once in a while?"). Did we expect these answers from the 69-year-old? No. But did they make us love her even more than we already do? Absolutely yes.

Any time you have a prim and proper British woman talk about topics of a bawdier nature, it's guaranteed to be funny. This sketch also gets bonus points for making Fallon almost laugh out of character. Okay, that's actually not that unusual for Fallon, but we always love it when we see it.

Monday night's "Tonight Show" was also Fallon's 100th episode. As you probably remember, Fallon succeeded Jay Leno as "The Tonight Show" host back in February, and he has dominated the 18 to 49 demographic in his late-night time slot. If Fallon continues his wacky sketches, stunts and musical numbers, which have also helped him turn "The Tonight Show" into a viral sensation, we're sure to see him continue this success for many more hundreds of episodes.
