Jack decides to go skiing with his buddy Bob. They load up Jack's station-wagon and head north. After driving for a few hours, they get caught in a terrible blizzard. They pull into a nearby farmhouse and ask the attractive lady of the house if they can spend the night. "I'm recently widowed," she explains, "and I'm afraid the neighbours will talk if I let you stay in my house." "Not to worry," Jack says, "we'll be happy to sleep in the barn."
Nine months later, Jack gets a letter from the widow's attorney. He calls up his friend Bob and says, "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 turns red and he says, "Yeah, I'm afraid I did." "Well, thanks a lot, pal...she just died and left me her farm."
