I thought it was the coffee, or maybe the Scottish buttheadedness. But no: it's a real live syndrome. Note that this newly-described malady, SIWOTI syndrome, sounds a bit like 'snotty' or 'so what-ee', so please be careful not to offend sufferers by mispronouncing the name, or by oversimplifying the affliction with crude cartoons. Via Pharyngula, a silly little blog written by one of the syndrome's most severely-affected victims.
