In honor of Jake and his joyful, boundless energy (especially at bedtime...)

It's fun turning somersaults
and bouncing on the bed,
I walk on my hands
and I stand on my head.

I swing like a monkey
and I tumble and I shake,
I strech and I bend,
but I never never break.

I wiggle like a worm
and I wriggle like an eel,
I hop like a rabbit
and I flop like a seal.

I leap like a frog
and I jump like a flea,
the must be rubber
inside of me.
