Most people can cure a case of the hiccups by holding their breath - this way...

Got the hiccups? Hold your breath - and keep holding it. 

According to Dr. Luc Morris, surgical oncologist at Memorial Sloan-Kettering Cancer Center in New York City, there’s a trick to holding your breath that can significantly improve your chances for success at curing the hiccups. First, take in as much air as you can and hold it for ten seconds. Then, don’t exhale. Take in a little more air - you can do it. Just five more seconds. One last tiny gasp and another five seconds. Now, exhale and breathe normally. Your hiccups should be gone. 

Hiccups are caused by spasms in the diaphragm and this 20 second three breath exercise relaxes the diaphragm and interrupts the annoying rhythm of the spasms.
