IDW Publishing Comics- What in Samhain Just Happened?! is the fourth one shot in a series of holiday-themed Ghostbusters comic books by IDW Publishing that released in October of 2010. The comic is also collected in IDW Publishing Comics- Haunted Holidays TPB.


When a media mogul seeks out the Ghostbusters to fix his haunted mansion, the guys decline, assuming it’s a Halloween-themed publicity stunt. However, Janine, angry about her pay, takes the job, claiming she knows as much about ghostbusting as the guys do. She’s soon in over her head, and the Ghostbusters have to race against time to save her before she’s yanked over to the other side forever. [1]

Television producer Artie Lester is haunted by a pumpkin-headed ghost and tries to hire the Ghostbusters to capture it. The Ghostbusters refuse when they learn Lester plans to film the bust and make it a television special. However, Janine secretly tries to capture the entity to earn the fifty thousand dollars Lester promised. Later, Janine is held captive by the ghost. At the same instant, the Ghostbusters learn Lester might really have a problem with a ghost, and that Janine dangerously tried to get him alone. The ghost is identified as Sam Hain, an escape artist and business associate of Artie Lester, whose mansion was taken over by Lester after he went missing and was declared dead. The Ghostbusters find a trapped Janine and Sam Hain. While Ray fires a proton stream at Sam Hain, Egon pulls Janine from a fading dimensional "soft spot" and attempts to trap Sam Hain, until he is told by Janine to let him go. Sam Hain then goes to the other side peacefully.


  • In the cover variant done by Dan Schoening, the Spider Witch from Ghostbusters: The Video Game appears in the mirror above the four Ghostbusters. Schoening's take on Spider Witch can be found on his Deviant Art Account: TraditionalDanimatio.[2]
  • There are many nods to Ghostbusters, The Real Ghostbusters, and Ghostbusters II in this story:
    • Sam Hain is a reference to villain Samhain, except he has a smaller head, antlers, and is more skeletal in appearance. He also is not a deity of Halloween, the only connection to it being that his ghost manifested around that time.
  • Page 1
    • "Who are you gonna call?" is quoted.
    • The DJ is holding a Ghostbusters LP album cover.
  • Page 4
    • A DeLorean from the "Back to the Future" movie franchise can be seen parked beside the Firehouse.
    • Peter and Ray mention business is slow, a reoccurring theme from Real Ghostbusters.
    • Janine's plant is from ″A Ghost Grows in Brooklyn
    • The magic lamp from "Janine's Genie" is on the file cabinet.
    • False alarms are mentioned, another reoccurring theme from Real Ghostbusters.
  • Page 5
    • Janine warns Lester no filming is allowed. A 20/40/60 news crew caused mayhem in "Egon on the Rampage" when filming during an experiment.
  • Page 6
    • Making appearances at children's parties is referenced, seen in Ghostbusters II.
  • Page 7
    • Artie Lester says he's heard of two brothers named "Remington...something like that," who are good with ghosts. This is a reference to the Winchester brothers from the television series Supernatural. Remington and Winchester are both famous gun manufacturers.
  • Page 8
    • Janine's car has license plate "GBI ZUL," a reference to Zuul in the first Ghostbusters movie.
    • Samhain's Two Goblin Minions make a cameo appearance as two decorations at Lester's house near the steps.
  • Page 16
    • Egon looks like he's working on that computer interface of Tobin's Spirit Guide from RGB or the Ecto Aroma Eliminator from "Masquerade"
    • Egon has a coffee cup with the periodic symbol for Cobalt emblazoned on it. He recited its atomic weight in Ghostbusters II to Ray as a rhetorical question.
