T o celebrate Saturday Night Live ‘s 40th anniversary, VH1 Classic is preparing to air the longest SNL marathon — or any TV marathon, for that matter — in history.
Beginning Jan. 28, the Viacom-owned network will air 433 hours’ worth of episodes, starting with season 39 and working back toward the very first episode, hosted by George Carlin in 1975. The marathon will run until Feb. 15, leading up to NBC’s three-hour anniversary special that night.
The marathon will not include every single episode, because some are simply too difficult to clear for issues like music rights, Variety reports . Plus, the network would not be able to fit all the hundreds and hundreds of episodes in the allotted time.
The previous record for longest TV marathon was held by FXX for its 12-day run of The Simpsons , but alas, VH1 Classic is about to top that.
Check out the full schedule , and get your cowbells ready .
