Evil caroller
From Tardis Wiki, the free Doctor Who reference
The Eleventh Doctor had to deal with some "evil Christmas carollers" while spending one Christmas with Amy and Rory. Unimpressed with their unoriginality, the Doctor rounded them and various other festive-themed threats up in the TARDIS, and invited them to Amy and Rory's to show them what a "real Christmas" should be like.
