An old guy confined to a nursing home was walking down the hallway when he noticed Mrs. Barnstone sitting on a chair in the lounge. He walked up to her and asked her if she could guess how old he was.

She replied, "Drop your pants and let me see."

Then after looking at him, she said, "Why you're 88 years old!"

"Why yes I am," the old man said, "how did you know?"

"Well you told me this morning at breakfast."
