Jack and his friend Rob went on a fishing trip. They packed their car and headed North, into the mountains.
After travelling for a few hours, they were caught by a storm, and luckily found a farm where they could seek shelter.
The farm was owned by a rich widow, who had a lovely big house with plenty of room, but she was reluctant to let them stay for the night.
She explained to the boys that she was worried that the neighbours might gossip.
The boys pleaded with her, and said they would be happy to stay in her barn, so she relented.
In the morning, the weather had cleared, and the boys went on their way.
Nine months later, Jack received a letter from a firm of lawyers. He drove over to Rob's house and confronted him.
'Do you remember that fishing trip, nine months ago, and how we stayed the night in that widow's barn?' he asked.
'Ah .. yes, I do', said Rob with a grin.
'And did you sneak up to her house in the middle of the night?' asked Jack.
Ahhh ... yes.'
'And did you happen to make love to her, and use my name instead of your own?' Jack insisted.
Ahhhh ... well ... ummm .... yes, I'm afraid I did.' Rob mumbled. 'I'm real sorry mate, I just couldn't help it. Why?'
'Well, she just died and left me everything.'
