Actually, I have heard that this is not uncommon among identical
twins.  One twin will be a mirror image of the other.  I remember
a book that showed pictures of twin's heads, with the hair growing
in whorls in opposite directions.

Does anyone know why this happens?  Are fingerprints reversed?
Come to think of it, are fingerprints the same on identical twins?
Why does this happen only sometimes?
