Grammar Cake

Speaking of square fondant-covered cakes:

National Grammar Day is coming up, and I'm planning a party.

I want to make a cake. A grammar cake.

But I have only two ideas, so I'm trolling for more.

My two ideas are:

--a basic rectangle, w/ fondant cut into letters that say: Grammar Are Great.

And then I'll use a piping tip and buttercream to draw editing marks that fix the grammar

--a series of cupcakes, each labeled w/ the name of a part of speech: (transitive verb, preposition, pronoun, appositive, etc.). 

I'll make the labels either out of something edible (writing w/ frosting, maybe), or print them onto pieces of paper, cut out, and tape to a toothpick.

My husband suggested creating a sentence in which the grammar is wrong because of the word order, and making a mini loaf of cake for each word.

Any other ideas?

(I have a cake idea for National Punctuation Day, but I'm saving it.)
