The episode was on yesterday when Wally took the boys camping and when Lumpy met up with them, Beaver said ,"Its not a bear, its dumb ,dumpy lumpy". I almost pee'd in my pants. There was another episode ,I forget which one , But as Beav was leaving He turned and said ,"Lumpy Dumpy Stupid ???? Then He Did his famous AAAAAAAAAHHHHHHH!!!!! Somthing about trying to make Lumpy feel guilty about Wally taking the blame for somthing, Anyone know?

The episode you are referring to is #137, "Wally's Track Meet." This is the episode where the coach catches Wally throwing wet towels at Eddie and Lumpy and kicks him off the team for a week. Beaver goes over to Lumpy's house and tries to get him to go to the coach, and tell coach that it was actually he and Eddie who started it, not Wally. When Beaver is leaving, he does the "ahhhhhh" you are talking about.

LOL! I thought of another one. It's where we first meet Lumpy and he bullies Wally & Beaver on the way to School. Ward tells the story about how he was tormented by a bully and trapped the bully by putting barrelhoops all around the driveway, hiding behind the house, and calling the bully names to get him to come out! Wally & Beaver get their own barrelhoops, go to Lumpy's house, and set them all over his drive way...Beaver and Wally both call out for Lumpy and Beaver (at least TWICE yells, "Lumpy Dumpy the big ape!" and Wally yells, "Hey Meathead, come on out meathead!" Fred & Mrs. Rutherford are eating breakfast and she asks him what that noise is outside, Fred says, "Oh probably someone looking for Clarence." Mrs. Rutherford hears Wally call out "Hey Meathead!" and says to Fred, "Might be for you dear!" and Fred storms out of the house falling all over the barrel hoops! One of LITB's funniest scenes and the classic "Lumpy Insult!"

Yep, that's another episode that I was thinking of as well. I know Beaver would always say "ahhh" to Penny or Judy whenever they were arguing about something. I always love it whenever Beaver gets insulted about something, and he comes back with, "well, I am not!" or "I did not!" LOL, classic.

In "Beaver's Report Card" there is another good one by Gilbert. Gil has just brought Beaver's report card to the house because Beaver had a dental appointment and left school early. Eddie and Lumpy answer the door while Wally is upstairs, and Gilbert just stares at Lumpy after he reluctantly gave them the card. Lumpy asks, "What are you staring at me for, Gilbert?" Gilbert says, "My mother's always telling me not to grow up to be like you, I was just trying to figure out what she meant."

I saw that episode!

There is another episode where Beaver calls Clarence, "Lumpy, Dumpy, the Big Ape!" Beaver, Whitey and Larry are washing Clarence's car, and Clarence starts calling Beaver, "Freckles." Beaver gets hurt inside, upset and leaves, but before leaving, he gives it to Lumpy by saying he would much rather be called Beaver instead of Lumpy. Then the classic line.....
