Pet Burmese Python:
Burmese Pythons are frequently quite tame in captivity, especially if they're captive-bred, but I once helped wrangle a Reticulated Python outside its cage — a species known to have a considerably nastier disposition — and that snake was possibly even longer than this one.
That happened at a friend's reptile breeding facility, and it was just the two of us in the room with this enormous tube of solid muscle and very long, sharp teeth. Luckily, that "retic" was calm and didn't give us any trouble (other than lifting it!) because this was before I started carrying, and I don't think there would've been anything we could have done to stop it if it mistook one of us for food.
