Boy (Return of the Spiders)
From Tardis Wiki, the free Doctor Who reference
A boy delivered pizza in High Wycombe.
One of his regular stops was the Fordyce home. Every night they made a large order. One night he encountered the Fourth Doctor and Romana. He told them of unusual nightmares among the citizens of High Wycombe and strange noises in the sewers. The Doctor offered to make his delivery that night, and gave him a bag of gold.
