From political sketches to celebrity impressions, there's nothing quite like Saturday Night Live. With 45 seasons since it began airing in 1975, the show manages to constantly stay fascinating, intelligent, hilarious, and relevant. That's no small feat, so we're definitely big fans and in awe of the people behind it.

SNL has made us aware of a lot of talented people, from writers to members of the cast, and it's fun to see which celebrity is hosting each week. But besides the amazing content on the actual show, there are a lot of behind-the-scenes happenings that we definitely want to hear about.

15 The Balcony Seats Are Considered Lucky Because They're From Yankee Stadium

The balcony seats on the set of SNL are considered lucky. Why? Because, according to Cheat Sheet, they're from Yankee Stadium.

SNL doesn't want to get rid of them, and they pay for them, too. We often hear about people in show business having certain rituals or superstitions, so this does make a lot of sense.
