 When Carrigan and Dibbs are trying to get the ghosts out of the  mansion, they first try a priest to exorcise them, played by  Don Novello (qv) as Father Guido Sarducci. When that doesnt work  the scene changes to several pieces of furniture being thrown out of  the door, and Dan Aykroyd (qv) is seen running out. He stops by  Carrigan and Dibbs and says, "Who you gonna call? Somebody else." He  then leaves quickly. The jumpsuit and the pack he is wearing  resemble those that his character, Dr. Raymond Stantz, wears in  _Ghost Busters (1984)_ (qv) and _Ghostbusters II (1989)_ (qv).
