Special Offer - Brains

A man is passing a butcher's shop and sees a sign:

Special Offer - Brains

Cow brains ------ a penny a pound

Sheep brains ------ 2 pounds a pound

Pig brains -------- 2 pounds a pound

Doctor brains ------ 50 pounds a pound

Engineer brains ------- 50 pounds a pound

Programmer brains -------50 pounds a pound

Lawyer brains ------ 1000 pounds a pound

He goes into the shop and says to the butcher "Excuse me, I couldn't help noticing your sign - I suppose the cow brains are so much cheaper than the other brains because of the Mad Cow Disease scare."

"That's right" says the butcher.

"And," continues the man, "I suppose the lawyer brains are so much more expensive than the other brains because they're such high quality."

"Not at all," says the butcher "do you know how many lawyers you got to kill to get a pound of brain?"
