Babies...
 All babies start out with the same number of raw cells which, over nine
 months, develop into a complete female baby. The problem occurs when the
 cells are instructed by the little chromosomes to make a male baby
 instead. Because there are only so many cells to go around, the cells
 necessary to develop a male's reproductive organs have to come from 
 cells already assigned elsewhere in the female. Recent tests have shown 
 that these cells are removed from the communications center of the brain, 
 migrate lower in the body and develop into male sexual organs. 
 
 If you visualize a normal brain to be similar to a full deck of cards, 
 this means that males are born a few cards short, so to speak. And 
 some of their cards are in their shorts. This difference between the male 
 and female brain manifests itself in various ways. Little girls will tend 
 to  play things like house or learn to read. Little boys, however, will 
 tend to do things like placing a bucket over their heads and running into
 walls. Little girls will think about doing things before taking any 
 action. Little boys will just punch or kick something and will look 
 surprised if someone asks them why they just punched their little brother 
 who was half asleep and looking the other way.  This basic cognitive 
 difference continued to grow until puberty, when the hormones kick into 
 action and the trouble really begins. 
  
 After puberty, not only the size of the male and female brains differ, but
 the center of thought also differs. Women think with their heads. Male
 thoughts often originate lower in their bodies where their ex-brain cells
 reside.  Of course, the size of this problem varies from man to man. 
 
 In some men only a small number of brain cells migrate and they are left
 with nearly full mental capacity but they tend to be rather dull, sexually
 speaking. Such men are known in medical terms as "Republicans."
  
 Other men suffer larger brain cell relocation.  These men are medically
 referred to as "Democrats." 
  
 A small number of men suffer massive brain cell migration to their groins.
 These men are usually referred to as.....  "Mr. President."
