On a special episode of "Jimmy Kimmel Live" Dan Aykroyd and Bill Murray discussed their most dedicated fans, naming a Hudson Valley man as the king of them all.

Peter Mosen has been a "Ghostbusters" fan since before the movie was even released. In 1984 Mosen won tickets to a special early premiere of the film. After reading up on the movie and checking out some publicity shots he thought it would be fun to arrive to the screening in costume. So, with the help of an old jumpsuit a friend found in a dumpster, Mosen created his own "Ghostbusters" uniform and showed up to the premiere.

Since then Mosen has been a diehard fan. Over the years he's built four replicas of the famous "Ecto 1" car, has made countless personal appearances and gained the attention of Dan Aykroyd, who Mosen calls a friend. In fact, it was Aykroyd who got Mosen a role in "Ghostbusters 2."

Look carefully in this scene. Mosen is the one who gets slimed at the table next to Bill Murray and Sigourney Weaver.

Mosen says he's excited about the new "Ghostbusters" reboot due out in a few weeks. Although there's been some negative online reaction from fans who've seen the trailer, Mosen says he's reserving judgement until he gets to see it for himself. Whatever the verdict, however, it's safe to say the Mosen will continue his reign as "king of the Ghostbusters fans" for a long time to come.
