Three blokes enter a disabled swimming contest. The first has no arms. The
second no legs, and the third has no body, just a head.

They all line up, the whistle blows and "splash" they're all in the pool.

The guy with no arms takes the lead instantly but the guy with no legs is
closing fast. The head of course sank straight to the
bottom.

Ten lengths later and the guy with no legs finishes first. He can still see
bubbles coming from the bottom of the pool, so he
decides he had better dive down to rescue him.

He pick up the head, swims back up to the surface and places it at the side of
the pool, where-upon the head starts coughing and spluttering. Eventually the
head catches his breath and shouts:

"Three long years I've spent learning to swim with my ears, then two minutes
before the whistle, some prick puts a swimming cap on me !!"
