This is just an unfinished room. I’m seriously about to block this magazine because a lot of low effort posts that get published here.
The other one I was in earlier was fine but this is literally just an unfinished room and someone stuck a chair in the corner. Probably a worker to take a break or rest his tools on.
Nothing here indicates it’s a joke. Nothing about the picture is funny or entertaining. Only the title mildly implies what OP is thinking but it isn’t written in a funny way. So maybe you should evaluate this question for yourself.
