Hunter wraps leg in towels, steps into snake hole and lets 20 foot snake swallow it

This is basically a completely ridiculous thing to do. Hopefully they ate the snake.  It is undeniably clever and brave. The audio is  in Greek but doesn't matter. Just go to 50 seconds in to get to the main event.

Can anyone identify the snake? It's weird to even acknowledge that this is a tactic you could potentially use if in a desparate survival situation. You're welcome for the tip. :) Have you ever eaten snake? I haven't...
