Pinky and the Brain:
Egad—cut the script short, Pinky, for we’re not quite alone
Oh geez, Brain! Indeed we are, but it appears Nick’s spliced some clones
They’ve made off with our schtick and their next stop’s my rightful throne
So before we conquer the world, we must take over the microphone!

Zim and Gir:
You’re the perfect parts for our Dark Harvest, judging from your names
Just one teeny-tiny little question: um, which one’s the brain?
Hey, wait a sec! They’re identical! Both simple-minded vermin
“one is a genius”—ha! Should’ve expected lies from earthlings
Even with the dated pop references you’re jamming in
your show’s plots are worse than yours—no one’s pondering what you’re pandering
Aww, Zim, they’re so cute! Can we keep these little rodents?
GIR, focus! That’d be hopeless, when we’ve already owned them

Pinky and the Brain:
You became a role model for pre-teens, acting quite moronic
but despite your many issues you're forgotten— like your comic!
With your products all rotting on the shelves of Hot Topic
Both your network and the Tallest made it clear you’re not wanted
Ironic that viewing your show is vomit-inducing
When your episodes all center around bodily fluids
Oi--he oughta vamoose quick if that’s the only flow he’s got
Seems he’s throwing up L’s; no wonder he’s green always—NARF!

Zim:
AGH! I’m immune to lice, but my head can’t stand your verbal tics
Though you’re correct—on the microphone, I am assuredly sick
Forsaken? No, we’ve taken over! Our names spread like a virus!
Our network’s revived us, while you got left with Elmyra
