在華特迪士尼的傳記中，有一段話寫道：「我們不想要米老鼠有一雙老鼠的手，因為他應該要更有人類的樣子，所以我們給了他一雙手套。不過，如果有5根短短的手指看起來又會太奇怪，所以我們只給他畫了4根手指。」（“We didn’t want him [Mickey] to have mouse hands, because he was supposed to be more human. So we gave him gloves. Five fingers looked like too much on such a little figure, so we took one away. That was just one less finger to animate.”）
