The Man with the Yellow Hat takes George to his checkup. George has never seen a doctor's office or a doctor before and becomes curious. After the doctor has to take a break, George puts on his coat and uses his equipment to try to track down a strange "bloopy" sound he had been hearing and, along the way, has to help several patients such as a woman with allergies a man with a broken arm and a woman with hiccups in the way only a monkey can.
