SNL50: The Anniversary Special

It's no secret that over the past 50 years, Saturday Night Live has become one of American television's signature programs. The culture-defining show has birthed the careers of many big- and small-screen stars—Eddie Murphy, Tina Fey and Bowen Yang, to name a few—plus a seemingly infinite number of catchphrases, characters and cowbell references (sorry, Christopher Walken). Tune in as SNL celebrates its own in a three-hour special on Sunday, February 16, at 8pm on NBC. Expect a medley of greatest hits, former hosts, funny moments, poignant moments . . . and Keenan Thompson.
