If anyone deserves the nickname "Spider-man" it is Alain Robert, the French skyscraper climber who holds the world record for most successful climbs of the world's tallest structures.

On March 15, he did it again by climbing a 31-floor office building outside Paris, specifically the 400-foot Mercurial Towers in the suburb of Bagnolet.

Robert has climbed more than 70 of the world's tallest structures, including the Eiffel Tower, the Empire State Building and the Petronas Towers in Kuala Lumpur, with his bare hands and without a safety net.
