Madge Monday

On Saturday we were choosing movies to rent. Yes, plural, I’m weak. For some reason Madge, who is the one in our family who runs out of the room when eerie music imposes its will on the action, wanted “Haunted Mansion.”
Coco didn’t. In order to convince him, she said, “Coco, it’s from the same producers as ‘Pirates of the Caribbean.’”
To which, of course, he said okay.
What the? A) Where does she get this, and B) What did he think she meant?
Maybe it merely shows that the marketing on packages is aimed at 4-yr-olds, but still.
