The Frozen Brain

During the middle of last summer an old lady wearing a thick coat and large hat was walking out of the supermarket when she collapsed. A doctor who happened to be going through the checkout at the time rushed forward to see if he could do anything.

Expecting her to be suffering from heatstroke he was very surprised to find it was actually a case of hypothermia! The riddle was finally solved when, to make the lady more comfortable, they removed her hat only to find she had been attempting to shoplift a frozen chicken under it.
