In a past life, I did some exam proctoring and had the unfortunate occasion to catch someone cheating. It was a simple, blatant, and decidedly low-tech affair of looking at the answer sheet of another test-taker. (There were also a set of identically-dressed, identical twins for that test, but that is another story.) Anyway, things have gotten much more high tech since then, and if this Reuters report is to be believed, possibly even life-threatening.

Students in China are inserting microscopic earphones into their ear canals in order to cheat on tests. Problem is, not all of these devices would get FCC approval. In one case, the device perforated the student's ear-drum. Please remember kids, nothing smaller than your elbow, alright? That is bad, but it gets worse.

Another student's earphones required an operation for their removal, the paper said, while an electronic device connected to headphones and strapped to a third student's body exploded, leaving a bleeding hole in his abdomen.

Umm, yuck.
