(Strip Number 730, Original Publication Date, 22 October 1984)
Panel 1: As Elly murders her free time at the ironing board, Mike pleads pathetically for a chance to have a Halloween party in order to show people that his family aren't ALL antisocial hermits like the nattering nabob of negativity with the ponytail.
Panel 2: Since she doesn't want to say no to his face, she tells him that she'll think about it. Anyone with a brain would realize pretty much immediately that her decision would be handed down some time next July. (As for replacing and/or repairing the malfunctioning iron punching its own little hole in the ozone layer, she'd sooner allow the party.)
Panel 3: Since Mike is kind of too stupid to realize that he's just been shot down, he stands there like an idiot.
Panel 4: His asking her if she can't think any faster than that surprises her.
Summary: This is because Michael has yet to learn that Elly doesn't speak English; she speaks the similar-sounding "Passive-aggressive Idiot". It sounds like English but words and meaning have as little to do with each other as possible.
