Poo tan

Imagine a wonderful beach in Greece. I am swimming in the ocean in the beautiful sea. Suddenly I saw a something strange light brown and bubbly sludge in the water. Oh no it is poo! I quickly walked out of the water passing a man going into the water. I said: It is poo in the water. He looked and said yes it is and he also left the water. After my swim in poo I wanted to leave but I saw the same man go back into the water with his daughter! Is he out of his mind!? Later we heard that it was a yacht who had dumped their toilet in the sea. So quick home and having a shower so I just have my tan and not the poo tan...
