Cheating
From Tardis Wiki, the free Doctor Who reference
Donna Noble claimed the Toymaker would cheat during his and the Fourteenth Doctor's game of Cut to ensure he won using his own cards. However, the Doctor assured her they could not: the Toymaker had to follow the rules of the game because they bound his existence. The Toymaker was distraught Donna would assume he would even think of cheating, remarking such a thought shameful. (TV: The Giggle [+]Loading...["The Giggle (TV story)"])
