So someone has developed a hiccup cure that looks a lot like a milkshake. Call me old fashioned, but the "OH MY GOD THERE'S A SHARK IN THE BOAT!" scare tactic has never done me wrong. And if that doesn't work I'll typically let weight lifters punch me in the stomach until I laugh so hard they go away. You know, now that I think about it- I invented something similar to this last year that looked a lot like a blender (well, it was a blender). And let me tell you- not only did it cure your hiccups, it cured your whole face.
