Dead, headless snake "comes back to life" to lunge at his killer

WARNING: GRAPHIC CONTENT
A video of a headless snake "coming back to life" and "lunging at" the man who killed it has taken over the internet by storm. The video footage, which was reportedly shot in Coosa County, Alabama, shows the snake, whose head had been shot off, "attacking" the man 90 minutes after it was killed, as per UNILAD.
Kerry Forbus, the wife of the man in the footage, explained the entire incident to the publication. She said, "My husband had just gone down to his garden to plow out the middle of his rows with a push plow. He got to the end of the row and hit the fence and went to turn around and that’s when he noticed the snake up against the fence."

"He grabbed his phone to call me just as I was leaving the driveway and told me to run into the house and get his gun. I ran and got the gun and took it down there to him. He shot the snake in the head with the shotgun and it blew the head to bits. He left it laying in the garden for about an hour while he finished plowing his rows out."
She continued, "Then he picked the snake up with the grabber tool and put it on the back of his truck to take over to show it to his brother. The snake did not move or anything when he picked it up and put it on his truck. He got to his brother’s house and that is when the snake started to move again! He killed the snake around 12:30 in the afternoon. This video was taken around 2:00 pm."

"After he got startled by the snake a few times he decided to just leave it in the back of the truck until around 6:00 pm. By then the snake was finally dead."
It should, although, be made clear that the snake was definitely dead after getting its head blown off, and the sudden lunging movements must have been the nerve endings that were still somewhat active after its death. But then, there's no way to be sure of that, is there?
