Over the weekend, a little wheelchair bound old lady rolled into the Louvre, up to the Mona Lisa, then suddenly jumped up and revealed herself to be an adult man, who then slung a custard pie at the painting, the threw a bouquet of flowers into the air, and then promptly got tackled by security.
10/10, an absolutely stellar performance. No additions to this story necessary.
Although no word yet as to whether or no the Mona Lisa was in on the prank. Couldn't tell if she was smiling.
