Mrs. Johnson, a pig farmer.

My favorite question from the boards went vaguely along these lines:*

Mrs. Johnson, a pig farmer, presents to your clinic with a one week history of a dry cough. She denies fever, nausea, vomiting, chest pain, or rash. She recently travelled to the Ohio River Valley to visit her daughter, who has leukemia and AIDS. On the way back, she visited several caves filled with raccoons and rabid bats. She is an avid gardener of thorny plants and also enjoys taking care of her extensive collection of exotic birds. Her husband, a snake and reptile enthusiast, smokes four packs of cigarettes a day and recently returned from a visit to a leper colony in subsaharan africa, where he was researching mosquito and parasite-born illnesses. As a hobby, the couple collects dust samples from the southwestern United States, and have been active volunteers at the local tuberculosis clinic. What is the most likely cause of Mrs. Johnson's cough?

(The answer, of course, is dilated cardiomyopathy from Chagas disease.)

Perhaps some other medical students can relate.
