Men enjoy mashing potatoes no matter what kind of utensil you give them to work with. Something about the need to smash things. But you will be having mashed potatoes every night if you get yourself one of the Bootprint Potato Mashers. Feeling like you are stomping those potatoes with a boot just makes it that much more enjoyable.
