Sometimes the wrong animals are in the cages...

We were at the zoo a couple of weeks ago, and an older brother (maybe 3 or 4) hit a younger brother (maybe 2), which prompted their mother to grab the older brother, yell at him, "No, hitting is BAD!", and then -- wait for it -- hit him as punishment, while simultaneously declaring yet again, "Hitting is BAD!" Talk about a confusing lesson!
