Reminds me of falling off a bike into prickly pear cactus. They go deep too, but at least thorns usually don't splinter more on the way out.
Ouch.

Ugh, when I was a kid in AZ, I stepped in an old prairie dog hole and fell into a big patch of prickly pears. I got covered in the things from mid chest to ankle. They hurt sooo bad coming out.

I was walking back from the bathroom in my home at like 3am one night. It was pitch black. I kicked a small container of toothpicks that had been sitting on the floor and stumbled. One of the toothpicks flipped out of the container and landed straight up just as my foot, and full weight, came down right on top of it. I ended up with the wooden pick sticking straight out of the bottom of my bare foot. They were standard ~2 inch picks, and it was probably buried about 3/4ths the way in. It looked exactly like what this guy had, but it went straight into the tissue of my foot, rather than glancing along side.
My partner drove me to the emergency room right away, and to this day I still feel the elation at learning it hadn't splintered or snapped off in the foot, and they were able to extract it pretty much in the same way he did. I got bonus tetanus shots for being such a good patient.
