Leaving Dan In My Will

A lawyer meets with the family of a recently deceased millionaire for the reading of the will.
'To my loving wife, Rose, who always stood by me, I leave the house and $2 million,' the attorney reads.
'To my darling daughter, Jessica, who looked after me in sickness and kept the business going, I leave the yacht, the business and $1 million.'
'And finally,' the lawyer concludes, 'to my cousin Dan, who hated me, argued with me and thought I would never mention him in my will. Well, you were wrong. Hi Dan!'
