medium
Explanation
This comic satirizes spiritualism and psychic mediums. A medium tells a client: "I'm getting a vision... yes, I can see him. It's your grandfather. He was loved dearly. He liked board games and he often wore a hat."
The client angrily responds: "Goddammit, this is how you're going to bullshit me?" -- implying that the vague descriptions are obviously generic cold-reading tactics. But then comes the twist: "You just a guy who's dead and gone beyond communicating with me from the grave, and all he wants to do is tell you to wear a hat!"
In the final panels, the grandfather actually does appear in the "spirit realm," saying: "Tell him I used to love to tell him about my hat!" -- confirming that the medium was, in fact, accurately channeling the grandfather, and the grandfather really was that boring.
The comic works on multiple levels. It first sets up the expectation that the medium is a fraud using generic cold-reading techniques (mentioning board games, hats, and being "loved dearly" -- all safe guesses). Then it subverts this by revealing the medium is genuine, but the afterlife communication is just as banal and disappointing as the skeptic assumed. The real joke is that even if psychic mediums were real, the messages from the dead would be trivially mundane, making the whole enterprise pointless either way.
