The percentage of times that a “fun fact” is actually fun is exceptionally low.
Yesterday, while working on a project about a Japanese bridge, Clara said, “Fun fact! This bridge has survived eight earthquakes because it’s built on a faulty line.”
My response: “That’s not fun.”
And no, it wasn’t. It was certainly a fact, but it wasn’t even slightly amusing. Nothing fun about it at all.
In most cases, the phrase “Fun fact” can most often be replaced with the phrase, “Fact!”
Perhaps, “Random fact!”
Maybe even “Interesting fact!” on occasion.
But almost never “Fun fact!”
