Quote from : Doctor Who: Dead of Winter Book

Really, awfully, terribly, I had a sudden attack of hiccups. I was staring at the Doctor, murderously angry with him. And hiccuping... 'That's it. I'm going down there. I'm offering myself to them instead. If you're too much of a coward.' The Doctor winced at that last word. I hiccuped again. 'Amy Pond,' he said. 'Try holding your breath.' 'I will not hold my breath! This is important! Rory is having his mind vacuumed and we're just standing here-' 'Hiccuping.' 'Yes.' We stood, glaring at each other. I hiccuped again. 'Seriously,' said the Doctor, patiently. 'I know it's not the best time, but really, try holding your breath.' I stood there. Hiccuping and scowling at him.
