The fifth season of Leave It to Beaver debuted on ABC September 30, 1961 with "Wally Goes Steady" and aired its last episode, "Un-togetherness" with Brenda Scott as Lori Ann, June 30, 1962.
This time, when the door opens, June appears carrying a tray that holds a full, chilled pitcher and four glasses, as the announcer intones, "starring Barbara Billingsley".
At the country club, Ward is greeted like a future in-law by the father of Evelyn, a girl Wally is dating.
When Wally plays tennis with Evelyn and her older sister Judy and her husband, who dropped out of junior college to get married, the Cleavers really start to worry.
After Evelyn's father leaves, Ward tells the man to let his son accept any invitation to visit the Hendersons.
Ward and June have been invited to the McBride's wedding anniversary on Friday, and Wally is taking Susan to a dance at the lake.
However, this sitter is Judy, whom Wally can't take his eyes off of, with a voice like a kitten's purr, and the good sense to disappear when Gilbert and Richard come calling.
Then come crashing sounds as Lumpy's car pushes Wally's newly purchased, non-running 1936 Ford coupe up the driveway.
Ward explains to Wally all the added costs having a car entails: $200 for annual insurance, a registration fee, and gas and oil.
The car is blocking the driveway and can't be pushed, so Ward and June have take a cab to a dinner date, while Wally calls Lumpy to bring "the guys" and tools.
The car is dissembled enough to be pushed out of the way, but Ward and June are shocked to return near midnight to find Wally and Beaver still working on it.
When the dealer arrives with his tow truck, to find the car picked over like "a boned fish", Wally is able to pay him $10 to haul it away, and still have $2.50 profit from selling the parts.
But when Uncle Billy's ten dollar cash gift arrives in the mail later in the day, Gilbert urges Beaver to keep the money a secret and use it to buy the car.
June knows her polite, conscientious son will get the job, as he does, and all the free ice cream he can eat, which makes any new worker too sick to want it.
Later that evening, Eddie and Lumpy pose as Mary Ellen's father, and phone to have Wally deliver ice cream to her slumber party, where boys are forbidden.
After being chased from the premises by a furious dad, Wally seeks out his friends at their homes and dumps some now melted pistachio on Lumpy, and a carton of vanilla down the front of Eddie.
Ward and June are found snacking on cream cheese and crackers—to forestall hunger pangs at the housewarming at the Burke's, whose lunches are invariably late.
Whitey calls Beaver and tells him that even though her family is moving, Penny will stay with her grandparents till the end of school.
Guests: Frank Bank as Clarence Rutherford, Richard Correll as Richard Rickover, Stanley Fafara as Whitey Whitney, Karen Sue Trent as Penny Woods, Alice Backes as Miss Lawrence, John Damler as Sergeant, Sid Kane as 1st Man, Jean Cook as 1st Woman, John McKee as Policeman, Jimmy Carter as Herman, Wally Wood as Boy, Lelani Sorenson as Phyllis (as Lei Lani Sorensen).
Beaver agrees to let June give his old electric train set, that he hasn't played with in over two years, to neighbor boy Johnny Battson.
Meanwhile, unbeknownst to the boys, Lumpy and Bill Scott have arrangements to pick up Wally late at night, after his basketball game, to go to a masquerade party.
Gilbert and Beaver, of course, don't know any of this and see this strange car complete with gangsters with masks outside their house late at night, and call the police.
Beaver visits his old teacher Miss Landers and his old fireman friend Gus, in order to receive positive validation of himself.
The tables are turned, however, when Eddie is the one who faints from fear on the roller coaster ride, while everyone else, including the Beaver, have a great time.
Eddie tells Wally and Lumpy that his dad is allowing him to quit high school to take a job as a local garage attendant.
The Rickover's washing machine is broken, so Beaver offers to help Richard take the family's clothes down to the laundromat.
Wally has promised to stay on the main road, but Lumpy and Eddie convince him to let them take a shortcut on the way home.
Eddie and Lumpy arrive separately Saturday night and try to scare the boys with sound effects of wild animals from a portable phonograph.
Ward tells them that they had no right to use his telephone to call or prank-call anyone without permission, and decides he wants all the boys to do yard work for him after school for a week to cover the extra cost.
Ward gives Wally a real-life lesson in economics by helping him and Beaver invest one hundred dollars in the stock market.
