Apparantly they are the 'brass monkeys' of cliche.
'Orangutang' is the sound they make swinging through the trees.

Eh??
Don't be silly, it's means "Old Man of the forest" in the local language.

Tell me you're messing.

Nope
The word "orangutan" comes from the Malay words "orang" (man) and "(h)utan" (forest); hence, "man of the forest".
