The Stupid-as-Diamond Lil story arc ends with a take-off on another recurring theme ... where Lil derides her fellow barflies, in this case Herman:
I have realized, as we continue this story arc where Stupid the Bird fills in for Diamond Lil, that many of the jokes don't make sense unless one is a regular reader of the strip.
For example, Lil and her best friend Edna -- both senior citizens -- often interact while looking out the window, as in this strip (a parallel to this one).
