There was this fellow who received a phone call from his doctor. The doctor said, "I have some bad news and some really bad news."

The fellow said, "let me have it."

The doctor said, "The bad news is that I got your test results came back and you have only 24 hours to live."

The man groaned, sobbed, and otherwise carried on. Finally he asked the doctor, "What's the really bad news?"

The doctor replied, "I forgot to call you yesterday!"
