A Lawyer finds out he has a Brain Tumor

A lawyer finds out he has a brain tumor, and it's inoperable -
in fact, it's so large, they have to do a brain transplant.
His doctor gives him a choice of available brains -
there's a jar of rocket scientist brains for $10 an ounce,
a jar of regular scientist brains for $15 an ounce,
and a jar of lawyer brains for the princely sum of $800 an ounce.
The outraged lawyer says,
"This is a ripoff - how come the lawyer brains are so damned expensive?"
The doctor replies,
"Do you know how many lawyers it takes to get an ounce of brains."
