Grandma's favorite joke

There once was a man that had a new overcoat. He went to see some friends and while there, had to visit the outhouse. When in the outhouse, he lost his coat down the toilet seat. When he came out, he explained his dilemma to his friend. His friend said, "Surely it would be easier to buy a new overcoat than to try and get yours out." The man replied, "It's not so much the coat, as the sandwich in the pocket."
