Zim as per his usual routine, goose-stepped merrily to Skool, his eyes closed and the space that his nose would have inhabited (had he been a filthy human) thrust wholeheartedly into the air.

He didn't notice a tiny, round puppy wiggle out of a dirty alleyway behind him.

Not anymore anyway.

The alley had been commissioned by the housing estates on either side of it in order to make them look more upmarket by comparison.
The alcoholic bums that lived in the alley were actually out of work sitcom actors on 8 dollars an hour.

"Hey the dog is leaving!" simpered a distinctly effeminate male voice from between a set of over-flowing trash cans within. "Uh, I mean uh, I sure am drunk…and homeless…I should probably find someone to urinate on now"
"Dude, bums don't say 'urinate', I can't work with such idiots," muttered a different voice within.

But of course this didn't matter, as Zim was ignoring the happenings of the alley with all of his mighty Urkan, ah…might. He merely continued to stride onwards towards Skool.

He soon paused to cross the street (an inane human ritual involving some liquid oozing female stopping vehicles mid-journey so that the insipid infant humans can reach the other side of the 'street'. Urkan motorists wouldnot stand for any such interruption. The insolence of these infants. This filth riddled planet…)

Upon standing there for a number of long, long seconds, one particularly revolting child managed to drool, "Hey, dahuh, that dog sure is duh, uh, dahuh…"

Zim examined the child in pompous bemusement.
"Dog! Why there is no dog here puss riddled classmate. Why would you insinuate such lies? LIES!"

The child continued to gaze at Zim in far off vacant stupidity.
"Dahuh, sure there is, duh huh, it's right behind you."

Zim twisted around to survey the sweetly slobbering, tailwagging ball of cuteness that was waddling up behind him.

Surveying the dog with only mild disgust (perhaps on account of the gut wrenching cuteness), there seemed to be some sort of connection between the dog and himself. As if Zim needed it for something or other. Hmmm, was it something to do with the barbaric human custom of 'homework'?

As he stroked his non-existent chin deep in thought, Zim experienced a little known feeling somewhere in his left shin. He felt that for once, he may actually be right…

"Hey, Green Kid."

Looking up, Zim recognised one of his idiot classmates addressing him. She hadn't been capable of speech the past few weeks so surely she had covered from her recent lobotomy (her parents could no longer afford the necessary Retalin supplements.)

"What did you bring for Show and Tell? I have the rest of my brain!" Drooling uncontrollably, she held up an ominous looking jar containing an inch cubed piece of gelatinous flesh.

Funny, thought Zim, I'm sure the stink child said they removed 80 per cent of the brain she housed in her filthy skull…

Realising he had to answer the revolting child's question, Zim's eyes fell once more on the dog behind him. Realisation dawned on him like a fiery Urkan mid to late afternoon.

"Why, I have brought this dog! Yes, yes it's all falling into place. I shall show you my dog and tell you about him as per the idiotic human custom."

Thoroughly satisfied with his skills as a covert operator for the Urkan military, Zim finished his journey in smug contentment.
