Satirical Art Brings Levity To London's Underground
London's mass transit system, known as the Tube, has been hit by a guerrilla attack by pranksters. Informational posters in rail cars have been covered up by stickers poking fun at the system. Shepherd's Bush stop was relabeled Shepherd's Pie. Priority seating in pranked cars now reads: "Pretend to be asleep and they won't ask you to move."
