These are all real, yet very rare ailments:
Maple Syrup Urine Disease - An inherited metabolic disease that makes the urine and sweat smell like maple syrup.
Prune-Belly Syndrome - An absence of abdominal muscles gives the stomach a wrinkled, puckered look and a severe pot belly that stretches out grotesquely.
Jumping Frenchman - An acquired condition first discovered in the 19th century among Canadian lumberjacks. Patients have extreme reactions to sudden noises or surprises: they flail their arms, jump in the air, cry, scream, and hit people.
Hairy Tongue - Due to tobaco is or poor oral hygiene, the tiny hairs on the tongue grow to be several inches long and the tongue itself turns black.
Foreign Accent Syndrome - After a severe brain injury or stroke, a person begins speaking their native language with a foreign accent. English-speaking Canadians might suddenly sounds Russian, for example.
Wandering Spleen - The muscles that hold the spleen in position are missing or undeveloped, causing the spleen to "wander" around the lower abdomen and pelvic region.
Alice-In- Wonderland Syndrome - Vision is distorted, making objects appear much smaller than they actually are. For example, a house may appear to be the size of a shoebox or a cat may look no bigger than a mouse.
