He's just a goat
A silly goat
A strange but still Billy goat

He's not a duck
Pressing his luck
Trying to stay a float

He's not a rabbit
With the nasty habit
Of steeling you favorite sock

He isn't the bother
Of that silly otter
Swimming under the dock

He's a goat
Not a boat
But a silly Billy nilly, goat.

He's not a dog
Or a green tree frog
Or a monkey with a hat

He's not a rat
Or an alley cat
Or even a turtle on a log

Nope.
He's just a goat
He's really a very silly, nilly,
Dilly of a Billy
Goat!
