It’s a Chrome extension with an ON and OFF icon, so you can choose whether to let him talk. When you click on your own Status Updates or other people’s posts, he bluntly spits out insensitive facts like “Nobody is really special” and “Everyone eventually dies” to remind you to constantly check in with what’s real before getting sucked into the dreamland of “I wish life could be like this.”
