Janine's car makes its first appearance in this episode. It is a little red VW Bug convertible. This is also the first episode in which the Ghostbusters borrow her car. They would borrow Janine's car in a number of episodes throughout the series.
Janine: If you're not downstairs in 5 minutes, you're fired.
Peter: She threatened to fire us?
Janine: Egon, wake up!
Egon: (half asleep) I'm sorry I burnt down the garage, Mom.
(The shower's spraying water all over the bathroom and the toilet's spinning in circles)
Peter: How come they never cover these things in Popular Mechanic? (the toilet paper starts wrapping around him) Ray! Can you come in here?
Ray: Wash your own back, Peter!
This episode was adapted into a book & cassette story on the Rainbow label (as with nearly all Rainbow adaptations of TV shows, none of the original voices or pieces of music were used on the cassette).
Out of the three episode adapted as such (the other two being 'Adventures In Slime And Space' and 'Cold Cash And Hot Water', this title seems to be the rarest.
