Of the Offthe Records hits from Morris Norris' time, "Without Math"/"Don't Leave, Just Stay, I'll Go" is the most often played on oldies stations.
Between its better quality and its interesting history...In life, the spirit in "Ghost of a Chance" ran an illegal gambling operation for the mob.
Once the poltergeist bride in "Ghost of a Chance" catches the delivery guy, he'll be killed, and will become another ghost haunting the house.
Alternatively... The poltergeist in Ghost of a Chance doesn't doesn't intend to harm the pizza guy; she's just really lonely.
She's a ghost, and presumably doesn't need to eat; the host didn't order takeout because she was hungry: he ordered it so she would have some company. The problem is, she's been cooped up in the house for so long that she's also gone a bit looney (hence why she screams at the delivery guy and chases him).
