Kangaroos?
Kangaroos?
Also, I see both of my dogs standing on 2 legs every day, often walking short distances like that. According to wikipedia this only happens when they are trained to do it (?!) but we never trained them and they've been doing it since a few months old. Maybe I should update https://en.wikipedia.org/wiki/Bipedalism to indicate training may not be required for temporary bipedal behavior in some dogs.
That is against wikipedia's rules and thus will get reverted. You have to have a secondary source, not a primary source, and you're currently a primary source.

Whether it gets reverted essentially depends on whether someone would bother before it gets lost in the depths of the change history and how the GP chooses to respond if someone did.
