my agent's brains

a cannibal goes to a butcher and ask for a pound of brains.

he's offered a pound of lawyer's brains for £25; a pound of doctor's brains for £50 and a pound of agent's brains for £100

the cannibal asks why agent's brain's are so incredibly expensive.

the butcher replies curtly : 'do you have any idea how many agents it take to make up a pound of brains?'
