Wikipedia:Don't poke the bear

Does he look like he wants to be poked? Bear: NO HUMAN DON'T POKE ME! *poke noise* GRRRRRRRRRRRRRRRRR!
Even the more harmless-looking variety might not appreciate being poked.

Bears are lovely creatures that often hibernate and are, for the most part, non-violent. However, when poked, bears can become quite angry. As such, it's always best not to poke the bear.
