Twenty froggies went to school, down beside a rushy pool,
Twenty little coats of green, twenty vests all white and clean.
"We must be in time", said they; "First we study, then we play;
That is how we keep the rule, when we froggies go to school."
Master Froggy, grave and stern, called the classes in their turn,
Taught them how to nobly strive; likewise how to leap and dive;
From his seat upon a log, showed them how to say "Kerchog!"
Also how to dodge a blow from the sticks which bad boys throw.
Twenty froggies grew up fast, big frogs they became at last;
Not one dunce among the lot; not one lesson they forgot;
Polished to a high degree, as each froggy ought to be,
Now they sit on other logs, teaching other little frogs.
