Funny Marine brains

[Eagledriver]

have this friend who went to the doctor and the doc told him he needed a new brain. The doctor took him down to this room with jars full of brains. My friend looks around and finds a jar that says, Doctor's Brains $1000/oz. "Wow he says I could be a doctor." He looks at the next jar and it says, Surgeon's Brains $10,000/oz. "WOW" he says, "I could be a surgeon." He looks at the next jar and it says, Marine's brains $1,000,000/oz. he looks at the doctor and asks, "Why are the Marine's brains so expensive?"
The doctor looks at him and says, "Do you know how many Marines it takes to make an ounce of brains?"
