"I'm talking to the people who are telling me lies!"

Today Cubebot 3's behavior is growing increasingly strange, as he sits in his chair, drinks coffee after coffee, watches Occupy TV on the computer, and makes noises every few seconds... harrumph, snicker, you racist pig, you lying scum, etc. Finally, I have had enough and I ask, "Are you talking to someone?" Cubebot 3 responds adamantly and points at the screen, "I'm talking to the people who are telling me lies!"
