Idiom- "The grass is always greener on the other side." This idiom is often used to compare that we always want what we can't have. We are always looking at other pastures and envying what they have rather than enjoying what we have infront of us. This image is a parody of the idiom becuase it is saying that really the grass is the same on both sides! There is nothing really separating the pastures except a few pieces of wire.
