As far as strange behaviour goes, this one definitely takes the cake. Pun intended. In news out of the Paris, a protestor disguised as an elderly woman has allegedly thrown cake at one of the world’s most famous paintings, Leonardo da Vinci’s Mona Lisa. And it’s not even her birthday! As far as we know.

While disguise might be something of an overstatement – in a video, the culprit can be seen wearing a rather bedraggled wig, lipstick and white jeans with a t-shirt. Hardly the dresscode of your average old lady. The art attacker, who it appears to be a French national, was able to get close enough by being pushed in a wheelchair. Once he was within arms reach, witnesses have described him jumping out of his transport and smearing the protective glass that (thankfully) surrounds the painting with cake. It’s believed that the protest was in regards to climate change, with some statements saying he yelled “think of the Earth!” while being led away by security.

In another video, he can be heard shouting “There are people who are destroying the Earth …,” and “All artists, think about the Earth. That’s why I did this. Think of the planet!”

As of yet, no one has confirmed what kind of cake it was.

Due to the Mona Lisa’s history of drawing unwanted attention to itself (it has had a teacup thrown at it, acid, a rock, has been stolen more than once) it has been encased behind bulletproof, anti-glare glass. All that was needed to fix the situation was a bit of Windex and a cloth.

The Mona Lisa has been described as “the best known, the most visited, the most written about, the most sung about, the most parodied work of art in the world” and is believed to have been da Vinci’s personal favourite among his works.

The 36-year-old has since been taken into custody and undergoing psychological evaluation and an inquiry into the incident is now underway for the crime of cultural vandalism. But seriously, the biggest crime was that wig.
