8. 'Saturday Night Live'
Live from New York, it's Saturday night – more than 40 years after the Not Ready for Prime Time Players first reinvented comedy as rock & roll. As Lorne Michaels likes to say, "We don't go on because we're ready. We go on because it's 11:30." SNL keeps that electric-edge energy running, even if that means flopping for episodes or even entire seasons at a time. Everybody thought the classic 1970s cast – John Belushi, Gilda Radner, Bill Murray, Dan Aykroyd – was too wild and crazy to replace. But noooo: SNL gave the world Eddie Murphy in the 1980s, Mike Myers and Chris Rock in the 1990s, Will Ferrell and Tina Fey in the 2000s, Kate McKinnon and Aidy Bryant today. People keep deciding this time it's really Saturday Night Dead, yet time after time it surges back. No other show has unleashed so many beautifully demented performers on the world.
