AWKWARD ZOMBIE

Replace the egg with a young Rarity being dragged along by her horn and you've got yourself a heretic meme.

It's on Facebook and Cheezburger. I haven't looked for it elsewhere. It's got a healthy ratio of people getting the joke versus people not getting it. Still, if I see one more "But you can't breed legendaries" comment I might do something untoward. It's thankfully balanced by the comments under each one going "That's the joke".

But you can't breed legendaries, Omni.

That's the joke.

This comic is horribly inaccurate.

How could an egg appear without Katie taking a single step?

Alright even MY first post wasn't that bad.

As punishment all further comic ideas Katie uses from me will be about Farmville and Miley Cyrus DS.

Since nobody seemed to mention anything, I will tell you, nice first post

It also made its way to /r/pokemon as well.
Where people actually not only got the joke, but also provided a source link (as it's against the rules to post rehosted comics).

So is it going to be a tradition to post a legendary-Cockfighting Society running away comic every 100-comic anniversary now?

Yes. One that roams and runs. Also the comic has to be written by someone other than Katie.

.. I must be missing something. Is that bread? It looks like a baguette.

I suppose it has been awhile since Katie had a sandwich..

It's an egg roll.

I thought it was a Cheeto at first.
