The Kiss

'You may now kiss the bride,' the First Doctor announced.
Adric and Nyssa leant towards each other, and kissed. The congregation applauded. Then waited. Shuffled their feet and cleared their throats. And waited a little bit more. In the back row of seats, several UNIT soldiers cheered and wolf-whistled.
The First Doctor coughed. 'You may now stop kissing the bride.'
The couple parted. Nyssa smiled sweetly at everyone. Adric's face turned red, then pale. He gasped for breath. Then he dropped onto the floor.
'Oops,' Nyssa smiled.
'I knew we should have thrown out that cyanide lipstick,' Doctor Seven muttered.
