The Image
It shows an old man shrugging with an arrow pointing to one of his knees and text beside it saying, "The ridges in corduroy pants are called "veep-veeps" due to the distinctive sound they make.*" The asterisk is red by the way, and speaking of asterisk, there's another one with text beside it as well, and it says (in red text), "*Actually they're called "wales." And they don't even sound like a whale, which is pretty disappointing."
