Jaws (Shark Song)
(actions in brackets)

(I've also come across numerous versions of this song with the word "shark" substituted for "Jaws".)

I've got a story (wave index fingers back and forth)
About Jaws (one hand over head as a shark fin)
Fetus Jaws (chomping motion with index finger and thumb)
Baby Jaws (chomp with two fingers and thumb)
Child Jaws (chomp with whole hand)
Teenage Jaws (chomp with two hands)
Adult Jaws (chomp with arms)
Giant Jaws (chomp using arm and leg)
Grandpa Jaws (chomp with two hands, fingers curled inwards i.e. toothless)
Lady swimming (front crawl)
Waster's flying (splash water up beside face)
Jaws swimming (shark fin over head)
Lady screams: (cup hands around mouth)
"AAK! Where's my leg?!" (hop on one leg)
Jaws swimming (one hand as shark fin above head, other patting tummy)
And that's my story (wiggle index fingers back and forth)
About JAWS! (clap hands, throw one arm forward and the other back as if saying "ta da"!)

Thanks very much to Sarah Wright, who sent me this version of the song! At her camp, they sing it as a repeating song.

This is the story, do-do do do
About Jaws, do-do do do
There was a mama Jaws do, do, do
There was a papa Jaws do, do, do
There was a baby Jaws do, do, do
And there was Jaws do-do do do
There was a lady do-do, do do
A pretty lady do-do do do
Just a-swimmin' in the sea do-do do do
But there was Jaws do-do do do
Shark attack Aaaahhh!!!
There was a man do-do do do
A muscle man do-do do do
He said "I'll save you do-do do do"
But there was Jaws do-do do do
Shark attack Aaaahhh!!
But there was more do-do do do
Jaws 2 do-do do do
