Asses as well as pitchers have ears. What does it mean?
I wonder not only it's final meaning, but also how the words of this sentence are connected with the meaning, because the phrase seems to be a nonsense.

Question

Answer

The original phrase was "Little pitchers have big ears" = little children hear (and understand) more than we think they do.
This is a play on the original meaning "Little children hear more than you think, but so do idiots and fools (asses)"

Answer

A handle to a pticher is an "ear". Both stupid people and pitches have ears. This would mean that anyone can hear something, even a "pitcher", but it may have little value. So don't pay attention to what stupid people tell you that  they have heard.
