Kookaburra sits in the old gum tree,
Merry merry king of the bush is he.
Laugh, Kookaburra, laugh, Kookaburra,
Gay your life must be!
although when i was a kid we added the line "save some gum for me!"
here's the reason why the song is stuck in my head.
p.s. i'm afraid of birds. it's this guy's fault:
i was also once bitten by a crazy-eyed parrot.
