When The Walking Dead returned from its holiday hiatus last month, fans learned that one of the zombies in the mid-season premiere was actually a tribute to Dr. Tongue, an iconic zombie from the George A. Romero zombie classic Day of the Dead. That particular movie was also the first gig for Greg Nicotero, who serves as a director, producer and special make-up effects guru on The Walking Dead. Greg Nicotero recently took to Instagram, where he revealed that this weekend's episode, Say Yes, features a tribute to another horror classic, the 1982 film Creepshow.

Greg Nicotero shared on Instagram a photo of a zombie who has been trapped in a box office booth. While you can't get a great look at the zombie itself, hardcore fans of Creepshow will immediately recognize this nod, since it references the iconic Creepshow poster where a gruesome skeleton with one eye is passing movie tickets through the box office window slot. Here's what Greg Nicotero had to say about this zombie tribute in his Instagram post, where he also revealed that this episode is his 19th as a director.

"Maybe a "Creepshow" tribute in this upcoming episode of The Walking Dead. My 19th episode as director. See you Sunday! All Rick, All Michonne, All Walkers! @amcthewalkingdead Off to London for @foxintchannels and @walkerstalkercon #creepshow #twd #knbefxgroup"

This reference continues a long tradition of paying tribute to iconic zombies from horror lore. In the penultimate Season 4 episode Us, many fans noticed that the Day of the Dead zombie "Bub" popped up as one of the many zombies that Glenn Rhee (Steven Yeun) and Tara Chambler (Alanna Masterson) had to fend off during a scene in a train tunnel. In Day of the Dead, Bub, played by Sherman Howard, wasn't you're typical zombie. Despite being undead, he actually remembered parts of his past life and could be taught how to perform basic tasks like listening to music. Other classic zombies referenced in The Walking Dead include the Plaid Shirt Zombie in the original Dawn of the Dead, the mud zombie from Lucio Fulci's Zombie and a reference to Jack Goodman's zombie corpse from An American Werewolf in London.

This particular zombie isn't trapped in a movie box office though, but the box office of an amusement park, which, in and of it self, may also serve as a tribute to the 2009 movie Zombieland. The end of that movie featured the main characters, played by Jesse Eisenberg, Woody Harrelson, Emma Stone and Abigail Breslin, trying to fend off a horde of zombies at an amusement park. The story follows Rick and Michonne as they head out in search of guns for Negan (Jeffrey Dean Morgan), while Rosita appears to be on a journey of her own. Take a look at Greg Nicotero's Instagram post below as we continue the countdown towards this week's episode of The Walking Dead, along with the original Creepshow poster.
