It reminds me of that period when people were taking a Garfield strip and removing the text and calling it a joke. I guess the humour was partly in the fact that there is no real punchline, so it creates a bit of an absurdist scene - people are examining an unfunny work closely looking in vain for something to laugh at. (Still unfunny in my book, but maybe I'm too much of a simpleton to understand it. )
