World's loudest hiccups

2 years ago I woke up with this annoying hiccup. 3 whole hours with this stupid hiccup. I even called emergency phone number. They thought I was just kidding. So I call them up again and said it was no joke. Nothing to do with it they said. My wife sit next to me and my son. I wish I didn't had this hiccup. After the last phone call I drank 1,5 liter coca Cola and ignored the hiccup then I put a finger fast in my throught. It all came up. And my hiccup stopped. I wish I never have this hiccup ever again.
