Believe it or not, this has happened to me! Fun fact, when I was younger I worked in a reptile facility and had a very similar thing happen to me. A snake (not the same type as the one in this video) bit onto my arm. The only way for me to get it off was to dunk it in a tank of water until it let go. If it meets it, it eats it...or tires to!
If you're weak stomached, viewer discretion is advised. There is blood.
