The Flintstones: Season 2, Episode 22

2 - 22: Operation Barney

Fred and Barney play hooky from work to see a ball game, but plans are foiled when Barney must report to his company's nurse, who, after Fred fixes it so Barney's condition looks "serious," is alarmed enough to send him to the hospital.. Fred's "operation" on Barney principally takes the form of applying a wrench to his nose and twisting with all his might, after which the patient's body temperature is, incredibly, normal. After finally escaping from the hospital, it's discovered that the ball game was actually scheduled for that evening – not that afternoon, as the guys had thought – and that Barney's boss had tickets for Fred and Barney to go. But because Barney was "sick," he gave the tickets away to someone else.
