Instead, we have Mike being a gullible sap who does stoooooopid things so he'll fit in and people will like him.
Panel 1: We start off with Mike with his hand in his mouth; the GAGG!! ULKKK!! noises he's making might make Lawrence smile but they alarm Elly.
Panel 2: A rightfully panicked Elly tells him to stop and asks him what on Earth he was doing.
Panel 3: He explains that Lawrence dared him to grab on to
Summary: This is because her brain is a God-damn Etch-a-sketch; every morning, she starts from Square Damned One and forgets that Mike does dumb crap like this because he thinks being a pliable fool will make people like him. He forgets that the people who dare him to do stupid stuff only do so so they can laugh in his face because he too has the memory span of a goldfish.
