Peter decided to go skiing with his buddy, Bob. They loaded up Peter's station wagon and headed north. After driving for a few hours, they got caught in a terrible blizzard. They pulled into a nearby farm house and asked the attractive lady of the house if they could spend the night.
"I'm recently widowed," she explained, "and I'm afraid the neighbors will talk if I let you stay in my house."
"Not to worry," Peter said, "we'll be happy to sleep in the barn."
Nine months later, Peter got a letter from the widow's attorney. He then went up to visit his friend Bob and said, "Bob, do you remember that good-looking widow at the farm we stayed at?"
"Yes, I do."
"Did you happen to get up in the middle of the night, go up to the house and have sex with her?"
"Yes, I have to admit that I did."
"Did you happen to use my name instead of telling her your name?"
Bob's face turned red and he said, "Yeah, I'm afraid I did."
"Well, thanks! She just died and left me everything!"
