Actually, you're right. If one considers comedy to be a form of art, then being purposefully inconsistent with the Oxford Comma can create comedic ambiguity. Unfortunately the author seems to dismiss those sorts of sentences as contrived.
Aside from that, I would contend that the vast majority of serial commas are incidental to artistic merit. If you're deciding on the Oxford Comma, you've already used at least one comma, and you're just deciding on the last one. That seems to me a pretty marginal decision.
