Empty Nest (1988)

Season 6: Episode 15

When the baby can't stop sneezing, Carol hires Studs With Suds to clean the house from top to bottom, and Sophia charges her friends to come and see them in action. But when they think it may be Dreyfuss causing the allergy, Harry takes him to stay with Charley, who doesn't want to give him back. Meanwhile, strange noises from upstairs make Laverne think the clinic is haunted by the ghosts of men who were murdered there years before.
