My name isn’t that common (how many other Littons do you know?), so when I always take notice when I hear or see it mentioned somewhere (on a microwave oven, for example).
Last night my wife was watching an episode of Ashes to Ashes and suddenly I heard references to a character called Litton. Within the first two minutes of the show I was treated to the lines “Litton’s a lying little bastard weasel-boy” and “Twathead Litton”. DCI Litton also had a tragic ’80s moustache, although (spoilers!) he turns good in the end.
