Happy Days - Season 10 (1982)

Howard's teen-aged niece, K.C., comes to stay with the Cunninghams after a scandal closes her Houston boarding school while Fonzie hopes a night at the circus will help him win little Heather's heart when nothing else seems to work.

Fonzie is challenged to a fight by a black belt karate expert who has nursed a grudge against him since the third grade and now wants to take his revenge.

Fonzie worries that the new popularity of folk music may signal more than just the end of his beloved rock n' roll.

Fonzie surprises Ashley...and himself!...by asking her to go steady with him after throwing a party to introduce her to his family and friends; but when jealousy raises its ugly head, neither of them are sure they're ready to commit.

Catastrophe looms when K.C. Cunningham reluctantly agrees to go to a costume party with socially inept Melvin Belvin after Marion encourages her shy niece to start dating.

When a new hardware store in the local mall takes away all his business, Howard must decide whether to fight or give in to the competition and say good-bye to Cunningham Hardware.

Roger tries to play it cool when his fickle former girlfriend, Lorraine, comes to town.

Hopes of reconciliation with her estranged parents appear to be ruined when nervous Ashley Pfister makes a fool of herself by drinking too much at their 30th wedding anniversary celebration.

Roger becomes concerned that Flip is falling under the influence of a gang of hoodlums who drink heavily. Flip tells his big brother to butt out of his social life. One night, the teen-agers get very drunk and become involved in a hit-and-run accident. The victim: Heather, making Roger's reaction the least of Flip's worries. What will the police - and Fonzie - say when they have their turn with Flip?

K.C. and the Cunninghams unintentionally derail Fonzie's plan to help a work release program convict get a new start as a mechanic when they treat him with suspicion after finding out his background.

Joanie and Chachi agree to work towards a common goal with their squabbling band members after Fonzie gets them a chance at a record contract; but what will they do when the record company agent tells them that the contract is only for the two of them and not the rest of the band?

Fonzie and Ashley remember the night of their momentous first date together when the Cunninghams throw them a surprise six month anniversary party.

The Fonz keeps his cool after a clerical error lands him and his 4-F knee in an Army reserves training camp just before little Heather's birthday; but he doesn't know that his commanding officer is someone he knows...and hates...all too well, and who believes that he finally has Fonzie right where he's always wanted him.

Fonz and Roger are going to a teacher's convention in another city but miss their flight. They hire Potsie's uncle to fly them in his old crop dusting plane, which could lead to high flying disaster.

An unexpected surprise waits for him at the church when Fonzie agrees to be former Falcon's gang member Jake 'Hey Fonz' Nelson's best man at his second wedding; Howard and Marion help K.C. rehearse for her school play audition.

Babysitter Fonzie makes a grave mistake when he listens to championship boxing on the radio during little Heather's tea-party; Joanie has more on her mind than Marion's mothering when she and Chachi head to the comfort of the Cunninghams after she catches the Canadian flu while on tour with the band.
