Saturday Night Live
Give Lorne Michaels a big round of applause—somehow, the television mogul has kept NBC's Saturday Night Live relevant and, most importantly, funny for 37 years. (In part with his great cameos.) Considering how many sketch comedy shows have come and gone during that time, that's nothing to sneeze at, especially when you take into account just how many careers Michaels has launched (from Dan Aykroyd all the way to sexy Kristen Wiig) with unforgettable skits and how many pop culture zeitgeist moments (i.e., Tina Fey as Sarah Palin) SNL has yielded.
Thanks to Hulu, you can watch every single episode ever, dating back to the show's October 11, 1975 premiere.
