Popeye

Popeye was a comic strip that Malcolm enjoyed reading when he was six years old in 1963. It had a character named Wimpy, who lent his name to London's Wimpy Bar. (PROSE: Time and Relative)

The Tenth Doctor described Popeye as being "hopelessly addicted to spinach and skinny women." Popeye's girlfriend Olive Oyl had a brother called Castor, leading the Doctor to joke that the spaceship Castor may have been named after him. (PROSE: Wooden Heart)
