Don't Fool With a Phantom - S2-E8
Shaggy: Hey, Scoob, aren't our wax statues the greatest?
Scooby: Yeah.
Daphne: Just what are you fellas going to do with those wax dummies you made?
Shaggy: Well like simple, next time we have a mystery, those dummies can go instead of us.
Fred: There's only one problem. How to tell one pair of dummies from the other.
Shaggy: Very funny, very funny.
Scooby: Yeah. Rery funny.
Question: We never found out what the ham and chicken bones had to do with anything. They were ham and chicken until Scooby ate them. Afterwards, Shaggy wonders why the ghost would keep ham and chicken in the fridge. This was never answered in the episode. Why were they important?
Answer: Shaggy told the gang he found ham and chicken in the fridge. He said, "Why would a ghost need food?"
Chosen answer: A ghost wouldn't have to keep any food in the fridge - they don't need to eat. So it is one thing that proves the ghost is not a ghost.
