(Strip Number 4312, Original Publication Date, 16 March 1983)
Panel 1: We find a baffled John going over his taxes as Lizzie looks on. As he ticka-ticka-tickas away at his calculator, he says that none of the figures make any sense.
Panel 2: As he continues on, he's alarmed by one of the figures he sees.
Panel 3: He then bellows the question "Has anyone been fooling around with the calculator?!"
Panel 4: Nizzie tell Daddy that she on'y did one ticka.
Summary: Since John doesn't believe in honest mistakes and can't wrap his brain around the concept that his children aren't trying to overthrow his authority, emasculate him and usher in an era of total chaos, we can probably expect him to smack her on the bottom for this. This is because the dumb bastard is too stupid to use an accountant like a regular person.
