"You knew what I was when you picked me up."
In the short video we saw it was about a guy that picked up a snake after the snake promised not to bite him. The snake was supposedly cold and hungry. When the guy and the snake went down the mountain, the guy dropped the snake and the snake bit him on the leg and then said "you knew what I was when you picked me up." This means that the guy already knew the rattle snake was dangerous and it was going to harm him anyways. The moral of the video was that is you pick up something that is going harm you don't do it. Think of the best decision which is the right thing.
