 Barney has a painful toothache. In order to save a bill from a dentist, Fred tries to help him snatch the aching tooth. Without luck, Fred brings him to a dentist for dinosaurs. However, the dentist puts too much gas into Barney s nose while he s on the phone that he "floats" away in the air. Fred must cope to keep Barney on the ground as his "floating" might get him into trouble. And mostly that he want to attend a big boxing match at night.
