You know how when one of your bestest, funnest, closest, oldest, pick up right where you left off-est friends is in town so you go out for a rager to all your old stomps...
You've got to take a selfie, it's like the law.
But you know how when you're taking a selfie
If you don't lift your finger up from the screen
it just keeps taking photos?
and you know how when you realize this, it's the funniest thing you've ever seen/heard/known?
what else is there to do then, but collapse into idiocy and hysteria?
And of course, keep your finger on the screen
(another warning: if you scroll too quickly, you'll probably get drunk)
It's like the law.
