Mrs. Murphy is looking for the grave of her late husband (a 
notorious criminal) as it has been a while since she was there.

She goes to the cemetery's management office and says, "I am looking 
for my husbands grave."

"Aye, madam," says the director. "What was his name?"  

"John Murphy," she answers.

He looks through his large book for quite a time and says, "Sorry, 
there are no John Murphys in our cemetery, nothing but one Mary Murphy."

The woman brightens up and says, "Of course that's it, everything was in my name."
