On the eve of his wedding to busty, blond 26 year-old Playboy centerfold Anna Nicole Smith US oil tycoon J Howard Marshall, 89, consulted his doctor.
'Doc, I'm getting married tomorrow and need something to pep up my pecker.'
'Sure, Mr Marshall,' the physician replied, 'here's a prescription for Honeymoon Viagra, just don't take it all at once.'
'Ok, Doc, but why the warning?'
'Well, prolonged sex with such a young lass could almost certainly prove fatal.'
'Don't you worry about a thing, Doc,' Marshall replies, 'if she dies she dies.'
