We have a guy who lives on the bench in front of my office who spends a good part of the day talking into his hand as if he's talking on a cell phone.
Sometimes his conversations are QUITE animated. He's even been involved in furious arguments.
From what I can glean, he's of the opinion that he's an operative in the government at a very high level, above the State Department and reporting to the White House.
Oddly enough, he lives in the park in front of the State Department annex where I work, and about a block from the Main State building.
It was from him that I learned that Darth Vader Dark Energy controls the US Military.
It all makes sense now.
