Rub a Dub Dub was a British nursery rhyme TV series animated by Peter Lang and Alan Rogers of the Cut-Out Animation Company that aired weekdays on Children's ITV from 17 October 1984 to 20 November 1984. The series was produced by David Yates and Joe Wolf.
The episode usually started off with the character Mother Goose and (most often) another character stood by a polka-dot patterned bathtub, with Mother Goose saying "Rub-a-dub-dub..." announcing that there was an item in the tub, an item that will then be relevant to the episode, e.g. "Rub-a-dub-dub, there's a kettle in the tub..." The line would then usually be followed up by another. In this case, the character King Crow appears at the window and says "...And King Crow wants his tea!" The nursery rhymes themselves would be dotted in amongst the humorous dialogue between the animal characters.
