Oprah, the President, and a Beatle sitting together in a box. It already sounds like the set-up for a joke. And luckily, comedian Chris Rock had a few jokes ready.

Oprah Winfrey and Sir Paul McCartney were at 'The 33rd Annual Kennedy Center Honors' (Tue., 9PM ET on CBS) to be awarded for "lifetime contributions to American culture." President Barack Obama was just along for the ride. (Being president is not as important as being a British singer or hosting a talk show where you give away cars, clearly.)

Still, since the ceremony was held in D.C., the Prez got to hang out with Oprah and Sir Paul, in a box seat above the stage. And Chris Rock had a few quips involving Obama and Oprah. "I walk in this room, and it's an amazing feeling to look up and see the most powerful person in the world," Chris said. " ... And right next to her ... Barack Obama." Ouch! Mr. President, you have been zinged.
