HEAT

   You think I would be untrue,
   you think I would be a liar,
   if I were to say to you
   that your swimming pool is on fire.

   But it actually and factually is.
   In flames like a burning tyre,
   incandescent like a Roman candle,
   your swimming pool is on fire.

   For your beautiful daughter is bathing.
   Her breasts and legs I admire.
   As long as she is in it, and of it,
   your swimming pool is on fire!
