There's no way I'd ever find the video, but I once saw a popular video on some SM platform where bears were harassing people in a bus, then one stands up and walks on two legs EXACTLY LIKE a bear mockingly imitating a person, as in "der, look at me, I can walk on two legs."

If it's the one I'm thinking of, it's at a park in South Korea(?) where many of the animals are former performers and/or have been encouraged to develop those behaviors to get human food. So the bear could be going, "Hey, I'm doing my trick, gimme my snack!" OR mocking the bipeds.😂
