There's an artist from England who calls himself Banksy. Recently he snuck his art into the major New York City museums, including this faux insect specimen he added to the Museum of Natural History.
This image is from a great collection on Wooster Collective.
I thought this was funny. I first read about it on MetaFilter this afternoon. This evening, the artist was interviewed on NPR's All Things Considered.
At least, it may have been him; the artist known as Banksy did admit that the interview might just be one more prank.
