DAMN IT!!!!! We're still stuck in the past!!!
Panel 1: We see Mike on the porch confiding to Lawrence that all he has to do is look at his mother and she gets mad.
Panel 2: Lawrence asks him if he was just looking at her and nothing else.
Panel 3: Mike allows as how she was taking a bath. The look on Lawrence's face suggests that the last thread of his heterosexuality has just died.
Hypothesis: Elly never heard of locking the door or realized that he couldn't maybe hold it in long enough to get to the other john. Since she can't think, Mike gets in trouble. Again.
