Hah, that reminds me of something I've seen a bunch of years ago !!
During a fair in Savannah, GA they had a "educational reptile show". They started talking about how endangered the Eastern Indigo snake has become. One guy brought this BEAUTIFUL Eastern Indigo out to walk around and show it off.
I watched the snake slowly and deliberately slither around his wrist and then open its mouth and latch on!!! I have to say..the guy kept his cool !!! LOL. I don't think many people even noticed what happened. I saw him grimace for a second and tense up, then he kept walking around with the snakes face attached to his wrist...hehe. He moved that arm below the other arm to try to hide the "bite".
The snake wasn't letting go, either. He finally walked (fast) behind the stage, lol..
