Head and Shoulder

Here's what happened.

My shoulders are messed up. Not too bad. But they dislocate with some recurrence. It started with a seizure years ago, and one dislocation makes subsequent ones easier. They're just loose, my man. I've been working on it, but solving it isn't really feasible without surgery, and surgery's gross. It also has its own uncertainties. But I actually have a trapezius now! That's a win.

Anyway, on Monday, I think that I found another new way to dislocate my shoulder, and this one's probably the weirdest. There have been a  bunch. I was dancing about as I was waiting for the train, and in this process, I briefly hopped up on a bench. As I jumped down, I banged my head into a sign, which wasn't a big issue for my head, but somehow the recoil or something knocked my shoulder out, and it took a bit of a while for me to pop it back in, diring which I was hobbling about in a pained hunch. I know that my brand is basically being the weirdest guy in the room, but it must have been especially strange to see someone hit his head and immediately start struggling with his shoulder. It was odd for me, and I at least had some idea of what happened.

Bonus Question! 

Are the Gyllenhaals the Cusacks of this century?
