GIR! What have you done? This isn't information retrieval! Are you insane?!
[in duty mode] I have captured the enemy for meat testing. Praise me! Praise meeeee!!
S1 E19GIR Goes Crazy and Stuff
[in duty mode] The knowledge, it fills me. It is neat.
GIR! You've drained enough humans today!
[in duty mode] Data canister is not yet full!
I command you to get out of here before we're noticed...some more.
[in duty mode] Your methods are stupid! Your progress has been stupid! Your intelligence is STUPID!
[Zim turns a dial, resetting GIR back to normal as he falls to the ground face first]
[out of duty mode] Hi Floor, make me a sammich!
That's better, I guess...
Heh, heh, sammich, sammich!
Curse you, snacks! CURSE YOOOOUUUU!
PSPoliceman Squid
I want to thank you. That was quite an adventure. The car wreck, the library fight and then, the galactic space battle that happened on the way to this beach.
Yes, yes, very nice. Now into the ocean with you, where you can tell no one of these things.
PSPoliceman Squid
I'm coming home! [Runs into the water]
Goodbye! Goodbye! Goodbye! Goodbye! Goodbye! [Happily to Zim] ...he's getting eaten by a shark.
[eating cafeteria food, gags] It's delicious! It's delicious! I AM NORMAL!!
Today, things are gonna change. I'm not just gonna sit around and let Zim get away with his... things he do. I mean-
[mockingly] "Things he DO"? What's your problem?
[Dib throws a muffin at Zim's head]
What? WHO?!
That... that was horrible.
[grabs muffin] WHO DID THIS?! Who dares to soil my normal boy head with this... PORK COW?!
PPoonchy
That's a stinking muffin!
SILENCE! Whatever this is, I will find the beast who threw it! I WILL FIND YOU!! Sleep peacefully now, for it is the last peaceful sleep you will know from this moment on!
CClassmate
But we're not asleep right now!
[Zim stares at the watching classmates before running away, screaming. Dib snickers.]
Actually, that was kinda funny.
[Dib is asleep in bed. Two aliens fly in and wake him up. They transform into shoes]
What? What's happening?! Who... what are you, and why did you transform into giant shoes?
We are beings of pure energy. This is merely a form your human brain can understand.
But you just looked like aliens before you turned into shoes.
Hmmm. Yes, but you couldn't comprehend that.
Yes, I could.
Why did you choose me?
You're the worthiest, Dib. And no one else had a head large enough to accommodate such power.
Dib... whatever your last name is.
That's right.
It's been nice working with you GIR, now self destruct.
Finally! [cackles, explodes]
DHDib Hologram
I will make you suffer large, alien!
S1 E20Hobo 13
With my mighty fists of horror and unstoppable cruelty, I am the tool of destruction, vengeance and fury!
I only asked for your name! Next!
TThrobulator
I am Throbulator! I am a creature of pure headache! Yeeow, my head!
Your name! That's all I want! Gah!
SSkoodge
Invader Skoodge, sir!
Skoodge? I thought the Almighty Tallest killed you!
SSkoodge
Yeah, but I'm okay now.
