It's all about not concentrating on the hiccup. Often, if you forget that you have the hiccups, it will stop. (Having a scare is all about that). A friend of a friend of mine was a young, immigrant taxi driver, and he got a customer that had the hiccups. The guy said that he had had them all day, and would do anything to get rid of them. The driver asked, like really ANYTHING? And he said, at least anything he could do. The driver then accepted the ride, and started driving. After driving for a while, when they were in an area known for having many immigrants living there, the driver suddenly blocked the brakes and started screaming "OUT OF MY CAR, NOW, GET OUT" with his thickest 2. gen. immigrant accent. He jumped up, got out and tore the door where the guy with the hiccups sat, and pulled him out. The customers (the hiccups guy was together with a couple of friends), were all shocked, and asked,"Whats happening?" and "What have we done wrong?" Then the driver seemed calm and nice again, and said the they could get in the car again. Of course they were even more baffled now, and was like, what was that all for? The driver then said, well, do you have the hiccups any longer? He didn't.
