The serial comma! Not all style guides see the need, but that final comma can keep the author’s meaning clear. For a costume, trace the outline of a large comma on the front of an old, solid-color T-shirt then use a glue gun to attach breakfast cereal (Kellogg’s Froot Loops, Post Alpha-bits, etc.) inside. Voilà, cereal comma. Bonus: Add some blood and gore if you want to be the version after an AP style editor has severed you from your sentence.
