Making you cry your eyes out like a wittle, wittle baby at the movie Up isn't as simple as you might think. In fact, there's a whole team of demented individuals at Pixar whose sole purpose is to make you feel as sad as humanly possible. This miserable place made up of tear-inducing scientists is the Pixar Sad Lab.
It's a place where tears = $$$
So go ahead and cry like a lil bitch, that's how the Pixar Sad Lab knows they've done their job.
