Critterature: Of Mice and Moose

If the plural of mouse is mice, And more than one louse is lice, Then it seems to me, that logically, The plural of grouse should be grice. A single goose duplicates into geese, A mongoose produces mongooses, So let me stick out my neck And ask why the heck The plural of moose is moose, And not meese, Or much better yet, Why not mooses? Author's note: Dear reader, if you're interested in a little more along this line, I invite you to take a look at my article/essay, "The Wonderfully Awful English Language".
