Sometimes the simplest things are the most funny.

Ever since taking over "The Tonight Show" from Jay Leno a couple of weeks ago, Jimmy Fallon has been calling on all of his A-list celebrity friends to keep "The Tonight Show" relevant and trending on social media.

Tina Fey appeared on the show with Fallon the other night and expressed some interest in interviewing herself.

What better way to do that than with an old-fashioned lip flip?

Again, so simple, yet very funny.
