The image you have provided is a photograph of a plaque with an amusing message engraved on it. The plaque is affixed to a surface, possibly a bench or a post, and is made from what appears to be a tarnished brass or similar metal, with the text in bold, capitalized letters standing out against the weathered background.
The text on the plaque reads "IN LOVING MEMORY OF ME I'M NOT DEAD YET JUST SELF CENTRED". This is a humorous take on traditional memorial plaques, which are usually dedicated to someone who has passed away. Instead, this plaque subverts expectations by first eliciting a solemn response only to redirect the reader to a comedic revelation that the honoree is, in fact, still alive and is jokingly self-proclaiming their self-centeredness.
What might make people find this image funny is the element of surprise and the twist on the conventional use of memorial plaques. The phrase "IN LOVING MEMORY OF" sets up a serious tone which is abruptly undercut by the declaration "I'M NOT DEAD YET," catching the reader off-guard and creating a humorous juxtaposition.
Further adding to the humor is the self-deprecating confession "JUST SELF CENTRED." Self-centeredness is usually viewed as a negative trait, but here it's presented in a playful, cheeky manner. The individual who created this plaque goes against social norms by openly embracing and announcing a characteristic that is typically frowned upon, which can be viewed as satirical or comically narcissistic.
The use of the word "JUST" implies a casual, light-hearted dismissal of any serious concern about the individual's status, reinforcing the comedic effect. By minimizing the significance of their self-centeredness in a manner akin to an afterthought, the individual implies a level of nonchalance and humor about their own ego.
Lastly, the plaque might also be seen as funny because it plays with the idea of legacy and remembrance. While memorial plaques are traditionally viewed as a way to honor and remember those who are no longer with us, this one pokes fun at the concept by ensuring that the 'memorialized' individual is remembered in an unconventional and humorous way while they are still alive, thereby leaving an unconventional imprint on the world.
