I talked to both the TV people about 30 times (I kept pressing the Z key, just to make SURE I would get it the wallpaper if doing this actually gives me it). Then I went and interacted with every goddamn thing in the room. Then I chainsawed all the NPCs in the room, just for good measure. And I did that twice. Well, on the second time I didn't chainsaw anything...but still, I got nothing!!
I guess I'll just have to try that, talking to the blue blobs and burning them again...
