A kangaroo.
Nobody truly knows exactly how to approach or react to a kangaroo. Half bunny. Half T-rex. It's just about the strangest animal on Earth.
It becomes especially entertaining when you bring it around neighbors with annoying ass dogs. In Chicago, most of the dudes I grew up with had pit bulls and rotweillers and tried to make them as dangerous and scary as possible. I'da loved to confront them with an adult kangaroo and laugh my balls off at their reaction and subsequent kangaroo attack.
