Mr. Jones was an old man with Alzheimer's who lived in a nursing home. One day he came out of his room, tracked down the nearest nurse, and said, "My penis is dead!"

The nurse kindly replied, "I'm sorry to hear that, Mr. Jones, but it happens all the time with men your age."

The very next day, Mr. Jones came out of his room with his penis sticking out of his pants and wandered up and down the hall. The same nurse saw him and said, "Mr. Jones, I thought you told me that your penis was dead."

He said, "I did - but today is the viewing."
