better extra toes them missing toes! you can remove extra toes, but I don't think you can get extra toes from a "toe bank" or something.
Come to think of it, a donated body parts organization would be interesting. Especially for plastic surgery. they could have a little Mr potato head doll, and you could put various parts on, "I want to look like this!"
Of course, in the meantime between you placing the Mr Potato Head Order onto the receptionists table with your Application form and money order, some 7 year old miscreant makes the mistake of thinking it's a waiting room toy. Long story short, you walk out of the hospital walking on one arm, an oversized ear, and carrying your suitcase with your giant moustache and one of your legs, and you have a huge hat attached to your but.
