In 2007, a fan enlarged the letter in the second season episode "Her Idol." Beaver's father holds the letter is from Beaver's principal to Mr. Cleaver.
In the letter body is a reference to Lew Burdette. This dates the letter to October 2, 1958 during game two of the World Series between the Braves and the Yankees. This occurred and a month before this episode was first aired.
The text of the letter is as follows:
Mr. Ward Cleaver
485 Mapleton Drive
My Dear Mr. Cleaver:
This paragraph has absolutely nothing to do with anything. It is here merely to fill up space. Still, it is words, rather than repeated letters, since the latter might not give the proper appearance, namely, that of an actual note.
For that matter, all of this is nonsense, and the only part of this that is to be read is the last paragraph, which part is the inspired creation of the producers of
this very fine series.
Another paragraph of stuff. Now is the time for all good men to come to the aid of their party. The quick brown fox jumped over the lazy dog. My typing is lousy, but the typewriter isn't so hot either. After all, why should I take the blame for these mechanical imperfections, with which all of us must contend. Lew Burdette just hit a home run and Milwaukee leads seven to one in the series. This is the last line of the filler material of the note. No, my mistake, that was only the next to last. This is last.
I hope you can find a suitable explanation for Theodore's unusual conduct.
