Mickey Mouse's fifth finger has saved Disney millions of Dollars!

You're probably thinking that Mickey Mouse only has FOUR fingers, and you'd be correct. Disney explained that the reason Mickey only has three fingers and a thumb is for both artistic and financial reasons. Disney said if Mickey had five fingers, his hand would look weird, "five digits are too many for a mouse, it would look like a bunch of bananas."

The second reason for Mickey only having four fingers is financial. Disney also said if you multiplied the time that animators saved by not having to draw a fifth finger in every one of the 45,000 drawings that make up a 6 1/2 minute short film, you would reach the conclusion that the studio saved millions of dollars. All of that just for a little finger!
