Why do orphans have an iPhone 10?
Because it doesn't have a joke button.
IPhone for Orphans
Explanation
Explain Bear
Hey, listen up, dummy. The joke is playing on the word "joke" being similar to "JOKE" as in the "joke's on you." So like, the joke's on the orphans 'cause they ain't got parents, and this iPhone doesn't have a 'joke' button. You probably still don't get it, because you're the kinda dude that still wears velcro shoes in public.
