I saw Josh's video and the picture of the snake.
1) It was in his dishwasher, not his washer. His wife opened it and the snake fell from the top to the bottom.
2) He took it outside, and that's where he shot the video of it. It shook its tail like it had a rattle on it, but didn't. (Baby ones have just buttons there, I learned.)
3) Based on my memory of the picture, it's either an Eastern Massasauga Rattlesnake or an Eastern Milk Snake.
4) Based on Josh's job, it's probably a milk snake. Just because of the name! Besides, the other one is Michigan's only venomous snake. If you get a snake in your dishwasher, it seems too much that its bite would ALSO be full of venom, right?
