Tree was a controversial 24-metre (79 ft) high inflatable sculpture by the artist Paul McCarthy that was briefly installed in the Place Vendôme in Paris in October 2014 as part of a exhibition called "Hors les murs". Although officially described as a Christmas tree, it was widely criticised for its similarity in appearance to a huge green butt plug. McCarthy admitted that it was deliberately shaped as such as a joke.
