An old joke that my grandad told me. A rich man had invited a group of friends to his home for dinner. He was very much looking forward to this, but there was one problem: he had a horrible cold, and his nose was running. He said to his butler, 'Oh Butler, what shall I do? I cannot have my nose running everywhere while there are guests here?', to which the butler replied, 'I have an idea. If your nose is running, I will say 'Johnson's at the door, sir,' and that will give you an excuse to leave the room and wipe your nose.' The man was delighted. 'Genius!' he said, and they planned this for later. That evening, there was a knock on the door. The man opened the door, to see a woman, his first guest to arrive. They greeted each other, then he invited the woman to the table. Soon after there was another knock on the door, and a man appeared, and he greeted and invited him in, and this continued on until there were a good 6 people at the table. When it was time to eat, Butler brought out a bowl of soup to everyone. All was well again, until Butler noticed something: the man's nose was beginning to run! 'Eh, Johnson's at the door, sir,' he said, but the man did not notice. 'Johnson's at the door, sir?' he said slightly louder. 'Sir!' he shouted. The man, startled, looked at Butler. 'What ever is wrong, Butler?' he asked. 'Well sir,' Butler said, 'Johnson's in the soup.'
