Grab it behind the jaws (the back of it's head where the groove is) and slowly coax his teeth out of your skin. Once your BP reaches 4 feet, never handle him alone just for safety precautions. There's a video on Youtube with Expertvillage that tells you what to do in the situation. But the water suggestions other people mentioned are good too. Grabbing a snake by the back of the head is like grabbing a cat by the scruff of it's neck or tapping a dog on the nose. No harm if it's done gently
4 feet huh? I wouldn't listen to a thing Expertvillage says.
