Used to.
There was a guy in Soho doing the three card trick.
Salute the king, salute the queen and bow your back to the keiserine was his poem as he shuffled the cards.
Then a policeman was seen approaching.
Kicks the cardboard box so it becomes a flat piece of cardoard on the road and the gang runs away.
When the policeman entered the street he could see nothing.
They must have been commies.
Later they acquired Rolls Royces, signed agreements in the Hilton hotel, now they run the country.
