Poooooor Mr. Taylor! His bum may hurt. I think I know what he is experiencing. He might have a bacterial infection or Crohn's disease. (My childhood-friends dad recently died of colon cancer..)

If he is experiencing mucus and blood in his fecal matter, he most likely has one of these. Other signs that he may have these is pus in his stool, bloating, cramping, and tummy aches. Poor Mr. Taylor! He needs some good antibiotics.
