There use to be a show on Austar (can't remember the name of show) and it was about a woman (some sort of specialist) who would look into the foods of people with shocking diets then ask them to go have a poo then she would examine it in her laboratory (omg, why am i laughing right now typing this) anyway, she would tell these clients about there poo and one time she did get a male client to get his ' system ' flushed out & they showed the cr@p going down this thick clear tube that you could see ' everything', yukkkk .... BUT he didn't look uncomfortable !!
