Here's a German song my father used to sing to us while bouncing us on his knee. At the end of the song, you are supposed to drop the kid on the floor. Very German. But we loved it!

Hoppa Hoppa Reiter

Hoppa, hoppa Reiter
Wenn er fällt
Dann schreit er

Fällt er in den Graben
Fressen ihn die Raben

Fällt er in die Dornen-Hecke
Macht er eine Stacheldecke

Fällt er in den Sumpf
Macht der Reiter Plumps

Here is a loose translation:

Hop, hop goes the rider
When he falls,
he screams

If he falls in a ditch
the ravens will eat him

If he falls in a thorny hedge,
he will become a pin cushion

If he falls in the swamp
He will go glug glug (or thud)

I wonder how this would go over at a baby storytime. (You don't really have to drop the kid on the floor)
