9th Doctor:
Frankenstein and his wife. I mean he is Mister grumpy after all. After some green paint and fake screws he easily fitted the part.

10th Doctor:
Bartley Crouch Jr and Bellatrice la strange from Harry Potter. You've always been a huge geek and The Doctor strangely reminds you of Bartley.

11th Doctor:
Two pirates. You borrowed an old pirate costume from the TARDIS closed and the next thing you know, you are in New York celebrating Halloween with the Doctor also dressed up as a pirate at your side.

Rory:
Two psyco nurses. You just took two of Rory's old uniforms, covered them in blood and bought some small accessories like a fake knifes and stuff. Rory couldn't stop saying how sexy you looked in his uniform, even if it was covered in blood.

Mickey:
Mickey and Minnie Mouse. You bought fake ears and everything. You thought it was funny because of his name. People thought you were the cutest couple ever.
