What you are looking at appears to be a standard After Hours Key Drop Box, but it's not. In actuality, it's a trans-dimensional portal. I know that's hard to believe, but it's true. Here's how it works: Step 1. Fill out an envelope
Step 2. Put your keys in the envelope
step 3. Put the envelope through the slot. The portal is now activated.
From here things get weird, as the portal seems to randomize it's output.
So far the portal has:
Deleted an envelope and put the keys back through the slot placing them next to the pens.
It balled up an envelope and stuffed it into an unlocked Pick Up Lock Box.
It moved keys from one filled out envelope into a blank envelope and then put someone else's keys into the filled out envelope.
It even folded an envelope up and stuffed it through one of the exhaust vents on the far bay door.
If anyone can refer us to a reputable paranormal investigator we'd love to get to the bottom of this. Or better yet, a priest who specializes in exorcising prankster demons. In the meantime, consider writing a short blessing on your envelope to help ensure safe passage through the portal.
