Puns of Fun, etc. etc.

Have you heard of the musician who made a note of everything?  He was either very sharp or fell flat.

Then there was the optometrist who made a spectacle of himself.

And the magician who turned his car into a telephone pole.

Of course, you've heard of the surgeon who loved to tell jokes in the operating room.  He was a real cut up, and always left his patients in stitches.
