The next morning Dib did what he never even thought he'd do before. He grabbed a lethal handgun from his Dad's lab he was working on, and marched to the dentist's office. Before he got there however, Keef awaited his appointment as screams and cries can be heard from the room. Not too long after Gretchen came out with torturous mouth piece yelling and panicking. "Quick! Tell me everything he did! Every detail." As she tried to explain her arms were desperately trying to get to her mouth as she tried to explain but it came out as gags and loud yelling. "Wow! Your really lucky Gretchen." After Gretchen had left, Zim came out in dentist gear. He looked over at Keef and the receptionist about to leave. "Does That earth filth have an appointment?" The receptionist rolled her eyes. "Ask him. I'm on break." And with that, she slammed the door behind her.

"You. Get in here." He said dragging him as Keef's eyes lit up. "What do you want?" Keef looked him dead in the eyes. "A root canal. A long slow, root canal." As he went into the office he rambled on and on about his old dentist. "I'm just incredibly devoted to her strength ya know?" As Keef was blabbering more, Zim grabbed fairly sharp tools for this procedure. Keef stopped talking when Zim pushed him back on the dentist chair. "Now lets take a look at that mouth. Say ah." Keef said Ah happily as Zim went to Work. Dib snuck in as he heard the sounds of yelling and "Wahoos! I'm gonna get a candy bar!" Dib
sat down slightly shoving the weapon on his coat pocket awkwardly sitting as he heard the sounds of Keef's....er...enjoyment.

  "Oooh!~ It's the professionalism I respect!" He blared out as Zim got out more tools. Dib still remained uncomfortably sitting as Keef continued to make noises. Finally he was done and Keef looked like he had the best time of his life. "Get out." Zim hissed. "What?" Keef asked "Get out of here." Keef stood there. "GO!" He yelled pushing him out the door and making sure he left the office. "What a sick human." He said about to turn and walk back until he saw Dib. "Well well Dib. Here for an appointment?" Dib stayed silent. Zim pulled out a piece of equipment that had the sharpest end that Dib had ever seen. "If I used this it'll hurt right?" Dib nodded. "You'll scream right?" Dib nodded again nervously. "Then come in!" Zim grabbed Dib by the collar and shoved him into the office and into the chair. "Your in need of an appointment Dib." Zim went to a screen and turned it on, displaying a very dismantled mouth. "This is what it could turn into with out immediate action!" Dib yelled out as Zim pushed him back with a sharp tool in his hand. "I-it has rust!" Dib said nervously. "It's an antique. They don't make them like this anymore. Though, I want to enjoy your yelling Dib, really savor it. Let me get my gas mask on!"

Out of Zim's Pak, came a large gas mask containing laughing gas that he inhaled and exhaled into. He then started laughing inhumanly and constantly, as Dib readied his gun.

Now, do it now

While he's gassing himself to a palpable stupor

The timing's ideal and the moment is super

To ready and fore and blow the sick bastard away!

Now, do it now

Just a flicker of pressure right here,
right here on the trigger

And Y/N won't have to put up that pig for another day!

Now. For the girl.

Now. For the plant

Now. Yes, I will!....But I can't

  Zim continues laughing as hard as he could until he caught his breath "Oh boy Dib I'm flying now! Oh the things we're gonna do to your mouth...well! I think I had enough of this stuff, time to take the mask off." As Zim tried to remove the mask, it wouldn't budge. He did this again, but nothing moved.

  At this point, Zim was loopy off of gas and not at all like his normal self "Hey Dib guess what!"

  "W-what?"

"It's stuck!"

  "What?!"

  "The mask it's stuck! I can't get it off!" Zim despite his dilemma was laughing and continuing to do so.  "Hey Dib, lend me some assistance!"

Dib stayed silent. "Well."

Zim wheezed out. "Well?! He says well?! Dib I don't think you comprehend this."

Don't be fooled if I should giggle

Like a sappy, happy dope

It's just the gas, it's got me high

But don't let that fact deceive you

Any moment I could die

Though I giggle and I chortle

Bear in mind I'm not immortal

Why this whole thing strikes me funny

I don't know.

Cause it really is a rotten way to go!

What we have here is an ethical dilemma

'Less I help him get the mask removed

He doesn't have a prayer

True the gun as never fired

But the way events transpired

I could finish him with simple laisssez faire

  Zim continued laughing and giggling as he felt his chest hurt significantly.

Don't be fooled if I should chuckle

Like hyenas in a zoo

It's just the gas, it turns me on

But don't let my mirth deceive you

Any moment I'll be gone

All my vital signs are failing

'Cause the oxide I'm inhaling

Makes it difficult as heck to catch my breath

Zim stayed silent for a bit until he started to yell loudly at Dib.

"Are you dumb or hard of hearing?!?!

Or relieved my end is nearing?

Are you satisfied??!? I laughed myself to..." Zim began wheezing and wheezing and slowly lowering to the ground.

"Death?"

And with that, Zim dropped dead onto the ground.
