Yes, it's Pinky and the Brain.

The situation's changed, for there is no more Brain,

Pinky doesn't know, He's just feeling pain.

He really is so sad,

He used to be so glad.

He feels stinky because he misses Brain, Brain, Brain, Brain, Brain, Brain, Brain, Brain, Brain, Brain, Brain, Brain, Brain!

Brain just got too old, maybe he was too cold.

He was 5 years of age, all spent in a cage.

Now Pinky's all alone, too bad Brain had made no clones.

They're dinky; Pinky misses Brain, Brain, Brain, Brain, Brain, Brain, Brain, Brain, Brain, Brain, Brain, Brain, Brain, Brain!

Pinky: narf (sigh).

I always liked Pinky and the Brain, go on, flame me all you want, I can take it.
