A Christian, a Jew and a Muzzie gotten into a huge car accident that claimed all 3 lives and they all went up to heaven to meet G-d.
And G-d told them all if they would be so kind enough to hand me your brains for medical studies for cancer and other diseases I would pay you all a handsome reward.
So the Christian gave G-d his brain and, G-d looks and nods and pleased what he saw and rewards the man 50 billion dollars. The man said Thank you my Lord.
The Jew also gave his brains to G-d and he again looks and nods and is pleased what he saw, rewards the man 50 billion dollars. The man said Thank you my Lord.
Then the Muzzie gives G-d his brain, and G-d looks puzzled and befuddled a bit. He is actually shaking his head in disbelief and rewards the man 5 dollars. The Muzzie said to G-d.
" G-d you gave the Christian and the Jew each 50 billion and me only 5 dollars, why you gave them so much and me so little"
And G-d replied, " I can not give something at full price to something that is not fully used".
