There was once a couple of blind people. Every time they were about to have sex, they had to use a code. The man said "big smoke bubble", and the woman replied "bring two bags". Then they entered the next procedure. There was a thief who discovered this secret. Once when the man blind was not at home, he broke into the house and said to the woman blind "big smoke bubble", and the woman blind replied "bring two bags". So he took off his clothes and got down to business. Unfortunately, at this time the man blind came home, said the code "big smoke bubble", and the woman blind was startled and said: "Oh no, someone is hogging the smoke."
