If only so I can choose monkey, then I'm down with it, because then I resemble a human with more hands, better athletic skill, great intelegence AND the ability to climb very well. Its a win because I can still wear pajamas, my body won't change much. Growing the tail would hurt like hell, and I would probably have a large amount of hair growth everywhere, but thats all the fun.... Right? Oh, and if its free, like I'm a testing gini pig or something.
