Classic Poem

Mary had a William goat, William goat, William goat,
Mary had a William goat, his stomach lined with zine.
One day he ate an oyster can, oyster can, oyster can,
One day he ate an oyster can, and a clothesline full of shirts.
Oh, the shirts can do no harm inside, harm inside, harm inside,
Shirts can do no harm inside, but the oyster can.
