Lyrics:

There's a hippopotamus, a hippopotamus, a hippopotamus in my pool
There's a hippopotamus
A hippopotamus
A hippopotamus in my pool
How did it get there? How did it get there? How did it get there?
I don't know
How did it get there? How did it get there? How did it get there?

I don't know
There's a book by anonymous
A book by anonymous
A book by anonymous in my pool
There's a book by anonymous
A book by anonymous
And a hippopotamus in my pool

No, I've not read it
No, I've not read it
When it dries out I'll have a go
How did it get there?
How did it get there?
How did it get there?
I don't know

Someone must've been fooling around
Someone must've been acting the clown
Someone must've been taking the piss
Taking the piss and acting like this

There's a painting by Hieronymus
Bosch, by Hieronymus
Bosch, by Hieronymus in my pool
There's a painting by Hieronymus
Bosch, by Hieronymus
Bosch, by Hieronymus in my pool

How did it get there?
How did it get there?
How did it get there?
Sure beats me
Must be a late work, must be a late work, one of his late works
Obviously!

There's a Volkswagen microbus, a Volkswagen microbus, a Volkswagen microbus in my pool
A '58 microbus, a '58 microbus, a '58 microbus in my pool

A hippie is driving, a hippie is driving, a trippy old hippie poor, poor guy
A hippie is driving, a hippie is driving, I throw him a towel
Here, go get dry

Someone must've been acting real cute
Someone wearing a slippery suit
Someone must've come over the lap
Throw in a hippo and then a giraffe

There is Titus Andronicus, Titus Andronicus, Titus Andronicus in my pool
There is Titus Andronicus, Titus Andronicus wearing a snorkel in my pool

Now he's gone under, now he's gone under, now he's gone under
Worry not
Excellent swimmer, excellent swimmer, looking much trimmer
Than I thought

There's a woman with an abacus, a woman with an abacus, a woman with an abacus
She looks Chinese
There's a woman with an abacus, a woman with an abacus, a woman with an abacus
She looks Chinese

Not that I'm prejudiced
Not that I'm prejudiced
Not that I'm prejudiced, no, not me
Not that I'm prejudiced
Not that I'm prejudiced
Not that I'm prejudiced
That's not me

Thrown in a hippo, a little Dutch art
An actor performing a Shakespearean part
Summary book and Germanic van
Asian lady, isn't it grand?
Yes, yes
So grand
