For a short presentation about AI I am looking for examples where AI failed and therby shows the limits of itself.

I remember there was one examples, where an image classifier was given an image of pink animals (I think sheep) on a tree and classified it as "Birds on a tree". I think this example showed what AI might do if the given example is not represented in the training data.

But I cannot find that example anymore (and I need a source).

Anyone knows of exmaples, that are documented that I could give and show the problem in a similar way?
