"Hello, I'm an iPhone"
"And I'm a Pre"
Pre: "I am having some gas pains"
iPhone: "I have an app for that" <farts> "and 50,000 other apps"
Pre: "Oh" <looks down> "I only have 5,000, But I have this really cool app that lets my phone sound like a piano when I touch the keys" <plays a tune> "do you have an app like that?"
iPhone: "Apple says I don't need any apps like that"
Pre: "I see. I also have this app that <something>"
iPhone: "Apple says I don't need any apps like that"
Pre: "Oh. Surely they let you have an app like <something>"
iPhone: "Apple says I don't need any apps like that" (and don't call me shirly)
Pre: "Well, at least you have your " <farts> "other apps"
iPhone: <farts again><looks stupidly at the screen>
