LOL this is going to sound so retarded (because it is)

but here goes .... So my brother went swimming with his school and he said it was dirty and smelt and i asked him did you swallow any water or open ur eyes while you were under the water and he answered yes and i thought to myself what if someone pooped in pools and he opened his eyes and it went in his mouth i keep going over and over this in my head what do you guys think
