I was working in the lab, late one night,
When my eyes beheld an eerie sight.
For my monster from his slab began to rise,
And suddenly, to my surprise,

He did some math!
He did some monster math.
Some monster math!
It didn't cause him any wrath.
He did some math!
He liked it more than a bath.
He did some math!
He did some monster math.

From my laboratory in the castle east,
To the master bedroom where the vampires feast,
The ghouls were annoyed by his attempts to explain
Several mathematical concepts in vain.

'Cause they hate math!
Yes, they hate monster math.
Hate monster math!
It causes them lots of wrath.
Yes, they hate math!
They'd rather take a bath.
Yes, they hate math!
Yes, they hate monster math.

He measured the displacement of water
Pointed out errors in Harry Potter
Much to the annoyance of Wolfman, Dracula and his daughter.

He came back to the lab, and I disgustedly frowned,
Igor rolled his eyes, and barks came from his hounds,
When he said that he never had felt more alive
When he found the hundredth digit of the cube root of five.

'Cause we hate math!
Yes, we hate monster math.
Hate monster math!
It causes us lots of wrath.
Yes, we hate math!
We'd rather take a bath.
Yes, we hate math!
Yes, we hate monster math.

Out from his coffin Drac's voice did ring.
Seemed he was troubled by just one more thing.
He opened the lid and stood on his feet,
And said, "Why did my cousin move to Sesame Street?"

To do some math!
To do some monster math.
Some monster math!
It doesn't cause him any wrath.
To do some math!
He likes it more than a bath.
To do some math!
To do some monster math.

The next day my monster took a difficult test,
And it turns out that at monster math he's the best.
But if you think that everything's cool, you're wrong.
He still annoys Igor and I all day long.

By doing math!
By doing monster math.
That monster math!
It doesn't cause him any wrath.
By doing math!
He likes it more than a bath.
By doing math!
By doing monster math.
