Worms Up, Worms Down

Worms up, worms down,
Worms up, worms down,
Worms up, worms down,
Worms are hiding in the ground!
Worms down, worms up,
Worms down, worms up,
Worms down, worms up,
Watch out birds will eat you up!

Hold your forearm out in front of you, then hold the index finger of your other hand up behind your forearm, weave your index finger up and down with the words towards your elbow, then back towards the end of your arm.
