"You need my help, you worthless human?" Zim laughs. "Oh, this should be entertaining. I'll hear you out, but there's no way I'd work with you!"
Dib lets out a frustrated sigh. "Look, I don't want to be here either but we need to break into Moop-ing 10 and you're the only one with the resources to-"
"MOOP-ING 10? Why on Irk would you need to go there?"
Dib sighed again. "You know I have Tak's ship, right? Well, it detected that Tak is imprisoned there and it insists we rescue her or it'll destroy us!"
"Tak?! Why would I want MORE competition?" Zim shouted. "Why shouldn't I just allow her ship to destroy you? What do I get out of this?"
Dib groaned. "You little- you're a greedy bastard, you know that? What do you want? I'll offer you anything."
Zim smirked as Dib realized what he just said.
"You'll give me ANYTHING? Do you not know who I am? ALL I WANT IS THE DOOM OF THE EARTH AND YOUR UNDYING WORSHIP!"
Dib gulped, but Zim continued.
"But since I'm feeling generous, I'll settle for a sandwich and a back rub," he said.
Dib's expression became confused. "A...sandwich and a back rub? That's it?"
"DO NOT QUESTION ZIM!!" Zim shouted.
"What...kind of sandwich?" Dib asked.
Zim took a few seconds to consider his decision. Then leaned towards Dib and just said "...tuna."
"Can you even eat tuna? I thought you hated earth food." Dib questioned.
"I TOLD YOU NOT TO QUESTION ZIM!!" Zim shouted again.
"Oh...kay?"
"And the back rub has to be at least 10 seconds," Zim added. "Ideally a full minute."
Dib shuddered and a light blush snuck up on his face. Although, he pondered for a second. This could be the perfect opportunity to study Zim. Maybe he could...he quickly shook his head. NOPE nope, absolutely not!
"Fine" Dib growled. "We have a deal?" He reached his hand out to the alien.
Zim took his hand with a smirk. "Deal~"
