I am sorry, Mr. Evans...but we do not have the results of your fecal stool sample. But we do need you to report back first thing in the morning with the next sample. Please recall the procedure involved: you will need to save your defecation and store it in a cool environment for 24 hours. We will run your stool analysis in time to determine whether or not your belief that you have a parasite is founded on medical testing. Mr. Evans scratched his head. Another stool sample? H
