This is certainly Absurd, but not at all Humorous -- Westboro Baptist Church (Fred Phelps's) has written a parody of We Are The World called
Got Hates The World. They mean it. (Their version of "the world" seems to include mainly gay people.) What's really bizarre is the contrast between the nasty words and all the smiling faces. There is even a small child singing at the end. It isn't funny at all, but yet it's so completely over the top that I laughed anyhow -- in discomfort, I suppose, and in disbelief that anyone who made this was serious. But they are. And smug as Hell, if you'll excuse the simile.
