Potato Head Questions

Okay, I get the whole gender thing where little girls thought they couldn't grow up to be a CEO of a large corporation or President of the United States and all of that. But I'm confused about this: What was wrong with Mr. Potato Head? Did that name make little girls think they could not grow up to be a Potato Head? Is that a dream of many little girls, or even one? Why did the toy manufacturer decide to drop the Mr. and go with just Potato Head? What other reason could there be?
