You're a Mean One, Dr. Doof

You're a mean one, Dr. Doof,
You really are a grump,
You're as pleasant as a pimple,
You're as smooth as a lump,
Dr. Doof,
You're an empty tuna can that's been thrown on the dump!

You're a monster, Dr. Doof,
You give us all a scare!
You're as kind and gentle
As a rabid polar bear,
Dr. Doof,
I wouldn't touch you with a 100-year-old dusty chair!

You're a vile one, Dr. Doof,
I'm really sure of that,
You have all the charming cuteness
Of a one-eyed vampire bat,
Dr. Doof,
Given the choice between the two of you, I'd take the one-eyed vampire bat!

You're a rotter, Dr. Doof,
Your plans are so monstrous,
You're wacky and you're crazy,
You're so mischievous,
Dr. Doof,
You're as kind-hearted as General Grievous!

You're a foul one, Dr. Doof,
You're a moldy old french fry,
You're wicked and you're schemeful
That we can't deny,
Dr. Doof,
Your mind is so ill and twisted that it makes you even more insane than good old Brundlefly!

You nauseate me, Dr. Doof,
You ain't no Santa Claus,
Your nose is sharp and pointy
Like Wolverine's claws,
Dr. Doof,
You're a plate of expired spaghetti sprinkled with grated moldy cheese and rotten tomato sauce!
