Is it art?

Roadkill teddies are currently being exhibited in an art gallery in Prague. The exhibition is called Decadence. It's appearing alongside such luminaries as Jeff Koons and Andy Warhol! Constable would be turning in his grave. Turner would frowning very forcefully in his urn. Rubens would be tutting very loudly in no uncertain terms. That's not art it's poppycock.
