Bloody Mary

Holly: "Daddy. Did you know that James the Fifth's daughter was called Mary Queen of Scots? And d'you know what else they called her?"
Daddy: "No."
Holly: "Bloody Mary."
Daddy: "Wow. I wonder why they called her that? I guess she killed loads of people."
Holly: "Hmm... I think she was exy-cuted, so maybe that's why because it would have made her bloody. That, or she maybe fell down a lot."
