A man visited a brain store to purchase some brain tissue for a study. Noticing a sign boasting about the quality of professional brains offered, he inquired about the prices from the butcher.
"How much for engineer brain?"
"Three dollars an ounce."
"How much for programmer brain?"
"Four dollars an ounce."
"How much for lawyer brain?"
"One thousand dollars an ounce."
"Why is lawyer brain so much more expensive?"
"Do you know how many lawyers we had to process to get one ounce of brain?"
