Naughty and nice list
Santa Claus kept a naughty and nice list to determine who was deserving of presents at Christmas.
The Eleventh Doctor consulted both lists when he helped Santa do his job one year. Names on the naughty list included Jeff Thompson, Shaun Lyon, Rick Marshall, and Barnaby Edwards, while one of the names on the nice list was Aaron Aaronson.

Frustrated with Santa, the Twelfth Doctor told him to go and write a naughty list. Santa revealed that he had, in fact, done so, and claimed that the Doctor was on it. He earlier recalled that Clara Oswald was marginal for the naughty list in 1993. (TV: Last Christmas [+]Loading...["Last Christmas (TV story)"])
The Thirteenth Doctor wondered if the list of children's names that "Mr Henderson" had in his office was the naughty list or nice list. (COMIC: Holiday Special [+]Loading...["Holiday Special (comic story)"])
