Tom and Jerry

Tom and Jerry was a cartoon on Earth.

Toshiko Sato told Ianto Jones that she had worked with mice long enough to know that their love of cheese was a cliché born out of old Tom and Jerry cartoons. (PROSE: Slow Decay)

After the Doctor regenerated into his Seventh_Doctor_(The_Lenny_Henry_Show) seventh incarnation, both he and Peri Brown decided to look into the TARDIS scanner on where they landed, but one of the channels was stuck with a Tom and Jerry cartoon. (TV: The Lenny Henry Show)
