Identical Twins
Identical twins are not the same
Although they share their genes
One may be quite insane
The other more serene
One may have schizophrenia
The other very stable
One has problems in his early twenties
The other fine and able
An MRI of the two
Shows very different brains
One with larger ventricles
The other in the normal range
The twins know themselves
That they are different people
Thank God for scanning technology
To prove them quite unequal
