Barney gets even with Fred because of his practical jokes he's been pulling on him from time after time, so Barney pretends to be a counterfeiter in his basement with his $500 bills of money he won in a slogan contest and Fred thinks the money is fake and will land him in jail. Meanwhile, Wilma and Betty try to cure the both of them of their practical jokes.

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.

Wilma's new cooking show on television is a hit with everyone except Fred, who's anything but a "happy pappy" as he's forced to go without Wilma's home-cooked meals.
