this little monkey goes bananas

I am the monkey,
No I'm not chunky,
It's all kinda funky,
When you're the monkey,

I scream and howl,
Beat my chest and growl,
Make thrusting motions,
It all quite foul,

I've got bananas,
No they aren't wearing pyjamas,
They're cruising through the Bahamas,
Yes my lovely bananas,

I am the monkey,
You might think I'm a little funny,
It's better than being dreary,
I, the bananamonkey,

I am vulgar,
Sweetened with sugar,
Hot and bothered,
I'll cut you no quarter,

I've gone bananas,
Most certainly lost my manners,
But not my bananas,
Assuredly I've gone bananas.
