Invader Zim, Season 1

Dib:
Look at him, Gaz! He doesn't like the cafeteria food.

[They look at Zim sniffing the food and groans]

Gaz:
I don't like it either. [mimicking while waving her hands behind her head] I must be an alien too, huh, Dib?

Dib:
[walks up to Zim] What's the matter? Scared of beans, space boy?

Zim:
Nonsense! I love beans. I love them…

Dib:
[hands Zim a spoon] Oh, just one more then? What are you scared of?

Zim:
Scared? Ridiculous. Witness my bean-chewing! [takes a spoonful of beans and reluctantly eats them, as Dib watches on with much anticipation] That's good eat- [retchs and convulses, ultimately falling to the ground] Yummy.

Dib:
[looks over table and sees Zim on the floor breathing hard, his head engorged with glowing fluid and pulsing] Look everyone! His head! That is so not normal! I was right all along, he is an alien! He’s Not Just A Alien, A BIIIG Brain! You never believed me, but now, I have proof! [Points to trail of glowing green goo leading out the door]

Zita:
You're crazy!
