The Nap

Under the shade of a maple tree
Sleeps a tiny, little snoring flea
Bedded down in the hair of a worn-out rat
That's sleeping soundly on the back of a fluffy brown cat
That's curled up tight on an old hound dog
That's snoozing on the back of a fat, pink hog
That's catching forty winks on the back of a cow
That's also asleep, though I don't know how
And under that cow sleeps an old gray mare
And can you guess what's under there?
Why, another little flea, at the bottom of the pile...
And I think it's going to be asleep for awhile.
