A pair of German protestors, protesting climate change — what else — threw mashed potatoes on Claude Monet's "Haystacks," which last sold for $110 million and was on display at the Barberini Museum in Potsdam.

The pair then knelt before the painting, so the cameras could get a good shot of them with their deed, and glued themselves to the wall.

So far this year these crazy climate activists also threw a cake at the Mona Lisa:

And tomato soup at Van Gogh's "Sunflowers":

And a wax figure of England's King Charles:

So far, they haven't managed to damage any of the paintings since they were all behind protective glass.

(No word on the king's face.)

"Today, October 23, Claude Monet's painting "Grainstacks" was covered with mashed potatoes by two "Last Generation" activists. Since the picture is behind glass, the immediate conservation investigation showed that it was not damaged in any way."

The protesters were arrested and charged with trespassing and property damage.

Hilariously, the media contacted the police and asked why the pair were being charged with "property damage" if the painting was behind protective glass and wasn't damaged.

What I find most funny about this pair is that they used super glue to stick their hands to the wall, which uses toluene as a solvent. Toluene is a liquid hydrocarbon made from fossil fuels.

(And that doesn't even count the oil used to make their clothes and phones!)

I'd throw some food at a priceless masterpiece in protest, but food's expensive these days; only the rich can afford to waste it like this.
