*Kyphosis, actually, but that doesn’t sound that funny.
I saw this image yesterday, and I chuckled immediately. It was a reflexive laughter, and it took me awhile to understand what exactly had triggered my reaction.
As I said, I laughed when I saw this, even before I had consciously processed what I had seen. A few minutes of heavy thunkin’ later, I realized what was wrong: they look ridiculous while trying to look cool, which is the worst kind of ridiculousness that exists.
