Personally though I find the ending of, The Tiger, the Brahmin and the Jackal to be more hopeful.
"After the tiger demonstrates what happened by jumping back into cage, the Jackal shuts him in. The Jackal then turns to the Brahmin and says, 'Might I humbly suggest, this time, we leave the Tiger in the cage?'"
Sane man. I too go after constrictors when I'm looking to milk venom.
