NEW YORK—Shaking his head in disbelief at what passes for art these days, museum visitor Francis Bach was reportedly heard muttering “Well, I could do that” to himself while viewing a Metropolitan Museum of Art security guard on his lunch break. “This doesn’t really seem all that impressive,” said the 46-year-old, noting the mayonnaise clearly visible all over the edges of the bread on the guard’s “haphazard, makeshift” sandwich, which was accompanied by a bruised banana and a diet Coke and clearly thrown together at the last minute. “Maybe I just don’t get it? But to be honest, I don’t think there’s anything to get. Ham and cheese on wheat bread seems like the most obvious thing in the world. My second-grader could come up with something better than that. I suppose it might be a comment on sandwiches or the food industry, but even so, it’s not like that took a lot of skill or vision to pull off.” Bach later changed his mind and expressed sheer wonder and amazement after getting really close to the seated guard.
