The episode was recorded on June 7, 1989.
This is one of the few episodes where the Ghostbusters get rid of the ghost without using their equipment.
Janine played a Debbie Gibson album on her stereo system. Debbie Gibson is an American music artist who started in the late 1980s.
After calling the pizza parlor to complain about their orders, they tell the Ghostbusters to go to the "rubber room hotel". Somewhat similar to what happened in Ghostbusters II.
Ray mentions eight calls having to do with Gremlins and Poltergeists all over the city. Both are entities the Ghostbusters have dealt with in the past.
