Surprise someone with a certificate from Santa letting them know they are on the Naughty List.
But there is the small print that if they are nice they can be taken off the naughty list.
Left blank so you can use for as many Naughty children, adults or even other halves.
Simple purchase, download, and print. Fill in their names and leave for them to find. Or to add to the surprise pop it in the post to them.
