This comic is actually three seperate comics.
In the first comic the Squirrel and Naepalm the chinchilla are walking along in a sunny day outdoors. They come across Hixie (Ian Hickson) who's head has swollen like a giant balloon's. He appears to be floating higher and higher up into the air.
Squirrel! Naepalm! I could use a little help here!
Hixie? What happened?
I overrode a sound, working consensus approach to adaptive images in HTML with an obtuse, problematic syntax!
So your ego is too big?
It's not big! I just know better than everyone else and don't need them!
Well, I could help you by scaling your head down to normal size, but this srcset attribute is a bit unwieldy and doesn't even work yet.
The picture element is clearly inferior! I'm infallible! Your lack of enlightenment has doomed me!
I wonder how high he'll go.
Knowing his ego, someone should warn the ISS.
In the second comic we find Justin McDowell standing next to the Squirrel. The Squirrel is wearing a fancy red dress. They are being confronted by Hixie, who is dressed in an expensive suit and appears angry. They are all standing on a theatre stage that is under construction.
For the last time, the standards WILL be re-written with the courtesan choosing me! I mean... the maharaja! I mean, with the adaptive image problem being solved by the srcset attribute!
What?! But the play... er... community group already crafted a better solution with the picture element!
I DON'T LIKE PEOPLE TOUCHING MY THINGS!
Hixie storms off.
Oh, Justin, what will we do?!
Don't worry, Squirrel! We'll just make a secret polyfill that we can use whenever we want other web designers know that we still care about rational and usable solutions!
In the third comic, Hixie is wearing a crown and standing in front of a castle. He appears to have strings attached to his limbs that go up into the air. A mob of people including Ethan Marcotte, Matt May, Dylan Wilbanks and the Squirrel. Several are holding torches, and storming towards the castle at night.
Down with the WHATWG! You're putting the browser makers over the developers!
Remember the priority of constituencies!
Time to go, Hixie!
Oh, hey guys! Want to talk about it? I'm sure you'll realize that Google and Apple know better than you!
Wait... are those strings? Is he a marionete?
The mob looks to the top of the castle, where they see Google Bot holding the marionette's strings and wearing a black hat and sporting a twirly mustache.
Google?! So Hixie HAS been a puppet of the browser makers this whole time!
... maybe? It depends on your definition of "puppet".
