One day, Dr. Smith, head of the family practice division at Sacred Heart hospital, is walking down the hall when a nurse stops him with a clipboard.
"Doctor? Could you please sign these forms?"
This was such a routine activity for Dr. Smith that he simply grabs the clipboard, took his pen from his shirt pocket, and signs without looking at the papers. He hands the papers back to the nurse and continued walking.
Only seconds later, the nurse stops him again. "Doctor, I think your pen is out of ink.
Can you please sign again?"
The doctor takes the papers and looks at where he signed. Sure enough there are only scratches on the paper in the shape of his signature.
He removes his pen from his shirt pocket to examine it when he realizes . . .
"Wait!? This isn't my pen. It's a thermometer. . . ."
"SOME ASSHOLE GOT MY PEN!!"
