Supernatural will soon reach its 300th episode, can you believe it? In honor of the huge milestone, set to air Feb. 7 at 8/7c on The CW, TNT is hosting a specially curated marathon of the show's Top 25 favorites.

Starting Monday, Feb. 4, you'll be able to revisit golden oldies like "Slash Fiction," in which killer clones turned Sam (Jared Padalecki) and Dean (Jensen Ackles) into wanted men, and "Mystery Spot," which found Sam reliving Dean's death over and over again thanks to the Trickster (Richard Speight Jr.).

However, there are a few key episodes missing from the list. Noticeably absent from the marathon are undeniable classics like "Baby," an inventive episode set entirely from the Impala's perspective, and "Swan Song," which might be considered the episode to watch. The breathtaking Season 5 finale gave Chuck (Rob Benedict) a beautiful send-off and delivered the ultimate gut-punch when Lucifer (Mark Pellegrino) murdered Bobby (Robert Singer) and Castiel (Misha Collins), and beat up Dean while possessing Sam who regained control of his body and locked both of them in the Cage.

Supernatural's 300th episode will see John Winchester (Jeffrey Dean Morgan) return and finally give his embattled sons some much-needed closure. Find out how you can relive Sam and Dean's epic journey to get to that milestone event by checking out the full schedule for TNT's marathon below.
