Welcome to the Navy Net aka Rum Ration

The UK's largest and busiest UNofficial RN website.

The heart of the site is the forum area, including:

  1. A biology professor at the University of Australia was giving a lecture on "Involuntary Muscular Contractions"
    to his first-year medical students. Realising that this was not the most riveting subject,
    the professor decided to lighten the mood slightly.

    He pointed to a young woman in the front row and asked, "Do you know what
    your arsehole is doing while you're having an orgasm?"

    "Probably out fishing with his mates!!" she replied.
