Sound Mind and Body?

From our friend Bundle Brent, one of the strangest wills ever, with clauses like:

Item: I give and bequeath Negro Cuff to the devil and himself as liberated from me and my heirs forever.
Item: I give and bequeath Negro Stephen to the Prince of Darkness and himself as liberated from me and my Heirs forever with three pounds a year for his travelling expenses in the Plutonian Regions to be paid out of my Estate during his life-

Imagine the scene when this was read out to the family!
