A couple of weeks ago I got a weird flat and intended to mention it.
I had a nail enter my tire from the side with the head. I thought maybe it could've gotten in at the point and then go all the way through and come out a second hole, but there was only one hole. And the more I thought of it, the less conceivable it seemed.
This was a new tire, by the way - a week old. The guy said, "They're good tires," but it's not my regular store and I don't trust him.
What I think happened was that the nail, which was medium sized, about an inch and a half to two inches long, had been lying on the side of the road for a while and had gotten a little rusty. The rustiness created a sharp edge out of the head of the nail, and this edge is what gouged and became lodged in my tire. It didn't stick in sideways - the point of the nail was perpindicular to the curve of the wheel. It was ridiculous.
