They're Pinky & the Brain.

Yes, Pinky & the Brain.

One is a genius, the other's other insane.

They're labratory mice.

Their genes have been spliced.

They're Pinky, they're Pinky & the Brain, Brain, Brain, Brain, Brain, Brain, Brain, Brain, Brain

Before each night is done

Their plan will be unfurled

By the dawning of the sun

They'll take over the world.

[Repeat]

They're Pinky & the Brain.

Yes, Pinky & the Brain.

Their twilight campaign is easy to explain.

To prove their mousey worth

they'll overthrow the earth.

They're Pinky, they're Pinky & the Brain, Brain, Brain, Brain, Brain, Brain, Brain, Brain, Narf!
