Kids do need to express themselves, especially in art museums. Stephanie Theodore took this image at the Tate Modern in London over the weekend, where parents allowed their child to climb onto a Donald Judd sculpture.

She tweeted out the photo, titled: "Holy crap. Horrible kids, horrible parents."

She added: "I told the woman the the kids were using a $10mm art work as a toy, she told me I knew nothing abt kids. Obv she doesn't either."

The artwork was apparently not damaged by the child using it as a play toy. Theodore said she did alert the museum staff to the situation.
