Saturday Night Live, the live comedy sketch show known for its vivacious cast members and ability to see the humor in current events and societal values, has been on the air since 1975. While the show has been at the center of controversy more than once during its four-decade-long run, loyal fans return to watch new cast members make them laugh every Saturday night. But in the show’s history of celebrity guest hosts and slapstick-humored skits, several Hollywood stars have been banned from reappearing on the show. So what exactly warrants a ban from one of the televisions most notoriously inappropriate shows? Read to find out! 1. ELVIS COSTELLO Suggest When singer, Elvis Costello, appeared as a musical guest on "SNL" everyone was excited to see what the musician would do. However, after interrupting another band to perform "Radio Radio," a song that criticized mainstream broadcasting, he was banned from television. When he was finally asked to return to the show, he performed the exact same stunt and was banned again. Some people never learn. 2. RAGE AGAINST THE MACHINE thinglink.com This rock band was invited to be the musical act for a 1996 episode hosted by billionaire, Steve Forbes. Before performing a hit song, the band decided to make a political statement that angered the crew, producers, audience, and viewers at home. They revealed upside-down American Flags on their instruments and outfits and were immediately escorted offstage, never to perform on "SNL" again. 3. CHEVY CHASE memegenerator.net The caring father in "Christmas Vacation" is not so caring in real life. After hosting "SNL" in 1997, Chevy Chase was banned from hosting the show ever again due to his demeaning and biased treatment of the cast and crew members during rehearsal. Although Chase can no longer host "SNL," he has made a few cameos on the show since his banning. 4. SINEAD O'CONNOR Suggest Irish singer, Sinead O'Connor, is not only known for her strong voice, but also her strong political statements. In a 1992 episode of "Saturday Night Live", O'Connor performed an a cappella version of Bob Marley's "War." What started as a beautiful piece ended in controversy as O'Connor protested organized religion with many offensive gestures. 5. CYPRESS HILL thechive.com Even though "Saturday Night Live" seems like a lively and carefree place, the producers have a strict no tolerance for alcohol and drugs on set. Apparently, no one told rap group, Cypress Hill, about that policy since a member thought it was okay to smoke a joint during a live performance. Obviously, they were never invited back. 6. ADRIEN BRODY pinsdaddy.com It's hard to believe that Adrien Brody, the actor who brought us to tears in "The Pianist," could be part of an offensive sketch. In a 2003 episode, the beloved actor decided to go off-script, sported dreadlocks and an awful accent when he introduced Jamaican singer, Sean Paul. This bad attempt at humor was enough to get him permanently banned from the show. 7. STEVEN SEAGAL Suggest Here's another actor who never learned how to play nice with the other kids. Action star, Steven Seagal was so rude to the cast and crew that one of the producers referred to him as "the worst host ever." His behavior was so bad that the producers debated having a host-less show. 8. THE REPLACEMENTS stereogum.com Like Cypress Hill, this punk rock band refused to adhere to the no drugs or alcohol policy. While performing rather tipsy singer, Paul Westerberg, cursed on live television. That was enough to get them banned for a few years. 9. MARTIN LAWRENCE Pinterest.com Comedian, Martin Lawrence, is known for his hilarious, but sometimes borderline offensive rants. But in a 1994 episode he took it a little to far in a sketch about feminine hygiene. His bit was so bad it was later removed from episode re-runs and he was banned from the show. 10. CHARLES GRODIN Pinterest.com The actor/comedian turned political commentator gave an awkward and unprepared performance in a 1977 episode. He skipped rehearsals and poorly improvised many of his lines. That was his first and last performance on SNL. Credits: hypertomb Share this story on Facebook with your friends.
