This House is MINE!
Explanation
The Joke
A ghost bursts out of a closet screaming "This house is MIIIIIINE! BEGOOOONE!" in classic haunted-house fashion. The living occupant calmly responds: "In this society, we do not recognize the concept of private property." The caption reads: "Communism really lowered the cost of exorcisms."
The Humor
The joke reimagines a haunted house scenario under communism. Ghosts traditionally claim ownership of a house to frighten away the living, but in a communist society, private property doesn't exist -- so the ghost's entire leverage disappears. You can't claim a house is "yours" when no one owns anything. The ghost is rendered powerless not by holy water or religious ritual but by political ideology. The caption's observation that "communism really lowered the cost of exorcisms" treats this as a practical economic benefit of abolishing private property, as if ghost removal were just another service industry disrupted by a change in property law.
