It's an example of where information is limited, but not logic. Theoretically, it's possible to out-think the guy when it comes to which glass contains the poison. The only time this wouldn't be true is if he used some random device beforehand to determine which glass he tainted.

All this reminds me of a childhood memory too... My best friend and I would often settle things by playing a game called odds and evens (best out of 5). I'd beat him almost every time. We joked about this, long after he moved away. Odds and evens is supposed to be 50/50. Clearly, it wasn't. But if my friend were smart enough back then to flip a coin to decide how many fingers he'd put out, it would've been.
