Leave It to Beaver : Season 6

June and Ward go away for a couple of days and leave Uncle Billy to stay with Wally and Beaver. Beaver quickly realizes Billy runs a much looser ship than Ward and June and feels as if he can get away with more things. However, he's soon in for a rude awakening when he helps Gilbert sneak into the movies.

June and Ward are excited when they learn that Aunt Martha has made arrangements to send Beaver to a prep school in New England. However, Beaver quickly realizes he will miss his friends as they are all entering Mayfield High School next year. This puts Beaver in a delicate position, how to tell Aunt Martha he doesn't want to go without hurting her feelings.

Wally has his mind pretty much made up about going to Ward's alma mater, State University and he's even considering joining Ward's old fraternity. However, both Eddie and Wally think twice when they hear from a college student that it's the worst fraternity on campus, but Ward has already sent out his letter of recommendation for both of them.

Eddie has been seeing one particular girl, Cindy Andrews and she wants to give Eddie a birthday gift, so she decides to knit a sweater. She uses Wally as a model and he begins spending so much time at Cindy's that he arouses the suspicions of Julie, Eddie, Lumpy, Beaver and his parents.

Beaver has been assigned to write a book report on The Three Musketeers. However he's waited right down to the wire to get reading and quickly realizes that he'll never get finished. He decides to watch the movie that's going to be on TV and write his book report based on the movie.

Ward is given two tickets to a baseball game and is faced with an impossible decision: should he take Wally or Beaver? Beaver lets him off the hook when he announces he has plans with Gilbert. However, when they fall through, Beaver changes his mind about the game and becomes convinced that because he's the youngest he gets the short stick.

A school dance has Beaver with a major dilemma: he has two girls who ask him to go with them. However, he has a little problem, he accepted the first invitation but now wants out of it when he's asked by the second girl. This leads him to take some of Eddie's poor advice.

Eddie is happy to break the news that he plans to spend his summer on a fishing boat in Alaska and this prompts Wally and Lumpy to think about signing up to do the same thing. However, they all get a dose of reality when they discover just what kind of conditions they would be living in.

It's come down to the final week before junior high school graduation and Beaver is having a ball and even skips a class with Gilbert. However, Beaver becomes convinced he won't graduate after Gilbert and him take a peek at the diplomas on Mrs. Rayburn's desk and find Beaver's diploma to be missing.

Wally and Eddie fall prey to Lumpy's practical joking after he plants cherry bombs under the hoods of Eddie's car and Wally's car. Both Eddie and Wally want to get him back but their plan goes awry when they destroy Lumpy's car after chaining it to a tree. All fingers point to Wally after Fred finds that the chain has Ward's name printed on it.

After graduation, an all-night party is set to begin, which has June and Ward very wary. They aren't sure if they should allow Wally to attend. Meanwhile, Wally's date for the party has the same problem. This leads her to invite Wally to meet her folks and put their worries to rest.

Beaver has the chance to travel around the country for six weeks during the summer and he's all excited about it. However, he quickly realizes when he's gone Gilbert will go after the girl Beaver has a crush on, Mary Margaret. Fortunately, he quickly realizes there's more to life than Mary Margaret.

Beaver's school is having a clothing drive and whoever brings in the most clothes is awarded 1000 school points. June, Ward and Wally round up all the old clothes they can find and put them in a box. When Beaver picks up the box to take into school, he mistakenly thinks Ward's nearby suits for the dry cleaner are also for the clothes drive.

While cleaning, June runs across an old family scrapbook and gathers the family together to reminisce about the past six years. The Cleavers recall scenes from previous episodes including: Beaver Gets 'Spelled, New Neighbors, My Brother's Girl, The Shave, Beaver Runs Away, Larry Hides Out, Teacher Comes to Dinner, and Wally's Election.
