Hiccup cures

[CHONGS]

Whenever I get the hiccups I get terrified that they will never go away and I'll have them for the rest of my life.  Luckily getting terrified is a good way to cure hiccups so it works out pretty well for me.

Whenever anyone has hiccups around me, I do the following:

Get serious about the situation, way more serious than one would otherwise get.  Have them sit down and explain to them clearly that they need to concentrate very hard and let me know just before they hiccup that they're about to hiccup.  So they sit there for about fifteen seconds, getting really embarrassed because they're all "LOL I Don't know!  This is hard!", all the while, without hiccuping.  Soon thereafter, they're all, "I think they're gone?"  to which I respond, "Exactly."

I use a slight variation of this that involves holding your breath and intense focus on some point in front of you.  My wife calls this the "black fly on a white post" technique.  The trick is to hold your breath until you can no longer hold it any longer...then count off 3 seconds in your head, and exhale.  95% success rate. 
(cases of extremely stubborn hiccups may require repeated attempts)

Usually works for me, except I exhale and hold it that way until the little dots explodes behind eyes. Works every time.

I don't smoke, but I keep a pack around just in case I get the hiccups. 

Works every time.
