So I just got back from the store where I got a hiccup attack. I quickly rushed home to catch them on tape. I complain about them and explain how I got them, but they came up quite randomly. Each hiccup is occasionally accompanied by a small burp.
I raise my shirt so you can see my stomach and chest contract in and out from the hiccups. I even toy with my nipples a little for your entertainment. The hiccups go on and off for about 7 minutes, then as suddenly as they arrived; they vanished.
