We have become aware of some complaints about the Aperture Time Commuter. If you see a portal to Hell in your home (or anywhere for that matter), don't go through it. Just throw something heavy, like a rock or someone else into it and it'll go away. If it doesn't go away after doing that and demons start flying out of it, you should probably beeline for a church because that isn't a Time Commuter problem. That's demons invading Earth.
