Twenty four little hours
A doctor walks into the room and tells his patient, "I have some bad news and some very bad news."
The patient, resigned to his fate, says, "Well, might as well give me the bad news first."
"The lab called with your test results," the doctor began. "Unfortuanately, you've got a rare condition and they said you have 24 hours to live."
"24 Hours!?" exclaimed the patient. "Thats terrible! What could be worse than that? What's the very bad news?"
"I've been trying to reach you since yesterday."
