Kookaburra Sits on the old..

Kookaburra sits on the old gum tree,

Merry merry king of the bush is he.
Laugh, Kookaburra, laugh, Kookaburra,
Gay your life must be!

Kookaburra sits on the old gum tree,
Eating all the gum drops he can see.
Stop Kookaburra, stop Kookaburra
Save some there for me!

Kookaburra sits on the old gum tree,
Counting all the monkeys he can see.
Laugh Kookaburra, laugh Kookaburra
That's not a monkey, that's me!

Alternative verses

Kookaburra sits on the electric wire,
Jumping up and down, with his pants on fire.
Ouch, Kookaburra, ouch! Kookaburra,
Hot your tail must be!

Kookaburra sits on a rusty nail,
Gets a boo-boo in his tail.
Cry, Kookaburra, cry, Kookaburra,
Oh how life can be!

Kookaburra sits on the old gum tree,
Eating all the gum drops he can see.
Laugh Kookaburra, laugh Kookaburra
Gay your life must be!
