Just remember, it is best not to fuck with a hippo. Even if you are a trained professional:
Hippos are incredibly cute and fun to watch. But they also seem pretty cranky and have a general aura of bad-ass-ness. This story actually reminds me of the South Park episode about the Crocodile Hunter Steve Irwin. In that ep, Irwin kept poking animals in the ass, then being attacked. Sticking one’s hand in a hippo’s mouth? Almost as bad.
