iOS vs. Android on Instagram sounds like South Park
It's a nice day. Stan and Cartman are outside playing, making weird poses, running around and laughing, and occasionally showing their phones to each other. Kyle walks up.
"Hey guys, what are you doing?"
"Oh, we're playing Instagram. We take pictures of us doing stuff, and then make them look old! It's great!"
Kyle downloads the app and starts playing.
Later, Kenny walks up. He mumbles something as usual.
"We're playing Instagram!"
Cartman says "Oh, but you can't play Kenny, because you're poor, and you only have an Android. Ha ha ha." Kenny flips him off.
The next day (insert guitar twang here), the boys are waiting at the bus stop as usual. Stan, Cartman and Kyle look decidedly unhappy. Kenny, meanwhile, is pumped. He's staring down at his phone, poking and prodding, and is holding his phone out at arm's length, taking crazy pics of himself. Then he sends them to the other boys.
Finally one of them goes "okay Kenny, that's enough, knock it off". Cartman says something else ripping on poor people, like "we don't want to see another picture of old burned out cars from your front yard".
"Just because it's on Android now doesn't mean you have to keep sending these crappy pics to us!"
"Yeah, it's only hip when it's a new car that only looks old and poor, not an actual old and poor car!"
I'm not sure how to end it. Maybe you flash over to Instagram HQ where there are a bunch of iOS users outside, yelling and screaming, protesting to get rid of the Android users.
Then you cut to inside, and a couple of people are looking out at the protesters.
"Still there, huh?" "Yeah." "Don't they have anything better to do?" "Guess not."
"So, want to go back to the pile?" "Yeah, I'm going to dive in this time."
They turn around and dive into an enormous pile of money.
Back in South Park, the boys find something else to do.
"Screw this. I'm going back to Draw Something."
