Condoms

Until 1900, condoms were made from an animal's bladder or intestine. They were expensive, fortunately they could be reused after being rinsed out. Then, however, they had to be dipped in milk first to make them flexible. The condoms were bought from the local drugstore. He kept the casing in the 'secret drawer'. Whenever a customer came, the druggist would pull out the casing along with a pair of scissors and dryly ask: 'How many centimetres, sir?'
