Google “The Lazlo Letters”. It is a collection of similar things from Lazlo Toth (who played Father Guido Sarducci on SNL). I found it amusing back in the 80s. He basically writes these nutty complaints to public figures and corporations. They generally are fairly civil.
I looked up Father Guido Sarducci because I knew he was played by Don Novello.
I never knew that Lazlo Toth was a pen name he used to write under. Something new...everyday.
