Runaway electrical impulses in the vagus nerve cause intractable hiccups, so Fesmire attempted to block them by stimulating the nerve. Gagging, tongue pulling, sinus massage and pressing the eyeball to stimulate the vagus all failed to stop the hiccups. Then he remembered reading about a case in which digital rectal massage - inserting a finger into a patient's anus - had slowed a racing heartbeat, an effect similar to runaway hiccups.So yeah, try one of those. Or both, if you're feeling adventurous.

However, Fesmire will not be trying it again. In researching his Ig Nobel acceptance speech, he told New Scientist that he found a treatment sure to be more popular with hiccup patients. "An orgasm results in incredible stimulation of the vagus nerve. From now on, I will be recommending sex - culminating with orgasm - as the cure-all for intractable hiccups."
Also, they say that if your hiccups last longer tha 48 hours, or if they're so severe that they interfere with eating or breathing, make an appointment to see a doctor.
