Gryffindor

Gryffindor was one of the fictional houses of the Harry Potter series. When Clara Oswald pointed out to three Doctors that their meeting couldn't happen due to a fixed point in time, the Tenth Doctor said "one point to the girl from Gryffindor". The Twelfth Doctor rebuked this, saying that she was Slytherin "all the way", and that he meant it as a compliment. (COMIC: Four Doctors)

Gwen Cooper once said "Ten Points to Gryffindor" to her husband, Rhys Williams. (PROSE: Almost Perfect)
