The song was performed by Kelsey Grammer as Ivan Krank
Krank: I was born with a brain,
That could not be contained
So they tourchered and teased me,
And called me insane
It was bad, very bad,
Even mom called me mad!
Any child would go wild from the pain!
Crazed with rage and defiance,
I turned my cerebrum to science
I tinkered and toiled,
Till my beakers all boiled,
And I built this amazing appliance!
Now the whole world will see the genius in me,
For I stand on the shoulders of giants!
Ha, ha, ha!
I am I, Ivan Krank
Just a man way ahead of his time
Allow me to be frank;
I'm much hipper than old Dr. Frankenstein
I am I, Ivan Krank,
And you may call me wacko or weird
But you'll have me to thank,
With this pup that you've reared
No longer wet-nosed, waggy-tailed or dog-eared,
He'll be human, like you, man, the world will all cheer
For the genius, which is I, Ivan Krank!
