You are never gonna believe this!
So, Ward went ahead and got the pet store owner to open up after nine PM, just so he could rent the annoying parrot for one day. He was convinced to do this because June, his wife, told her own personal sob story to him, about how when she was at boarding school, she was so lonely and homesick that she told all the girls that her mother was a big time movie star, Laverne Laverne. Her mother found out, and instead of backing her up, made her tell the entire school that she had made it all up. June was obviously still carrying shame over this incident, and encouraged Ward to get the parrot, and trust that the Beav would realize the error of his ways, and never put his parents in that kind of spot again.
The Beaver took the parrot to school for the Pet Fair, and won the Blue Ribbon, much to Judy's utter disgust. After the whole class left, Beaver tried to return the Blue Ribbon, explaining the whole situation, about how he lied because he was embarrassed his family did not own a pet. His teacher, Miss Landers, told him that was a very silly thing to be ashamed of, and that his parents were pretty great for backing him up like that. The Beaver told Miss Landers he would never put his parents in such a spot again, and he accepted the Blue Ribbon, after all.
I do not think anybody mentioned the new pet hamster ever again. They probably killed it.
In the next episode, Wally had to stay home all weekend and study for his history exam, instead of crash Mary Ellen Rogers house with Lumpy and Eddie Haskell. They were supposed to "listen to records and eat junk".
Lumpy and Eddie went to Mary Ellen's house without Wally, and told him they were not worried about the history test. They had it covered.
What that meant was that Eddie had come up with some cockamamie scheme to cheat on the test, involving them excusing themselves to wash their hands and get the answers, written on paper towels in the bathroom.
Unbeknownst to all three, the history teacher was wise to this scheme, and had planted a quote from Hamlet on the paper towel, removing the illicit answers.
Wally saw this first, however, because he legitimately had a pen explode on him, and actually had to wash his hands. Lumpy and Eddie went to the bathroom, only to find no answers, and both failed their exam, both scoring in the low fifties.
Wally, on the other hand, got a 92, one of the best scores in the class. After learning this, Eddie decided to get even, and wrote a pathetic attempt at an anonymous note, pointing the finger at Wally for cheating.
The very wise teacher, though, saw right through this, and confirmed it to Wally that Eddie and Lumpy were the rascals.
Wally wanted to beat Eddie up, but Ward convinced him not to. He said Eddie would have to figure it out on his own that had done a bad thing.
Sure enough, Eddie came over right then to apologize to Wally, and tell him he was going to try out "this studying thing" that was working so well for Wally.
The next day at class Eddie amazed everyone with his knowledge of the founding members of the League of Nations.
Then, Daniel Boone was captured by the Spanish Army. They wanted to take back the Virginia territories for Spain. I had to go to work, though.
