He's lying
Tranq'd a mountain lion from a helo on top of mountain so he could tag it. After he tagged it he had to carry it doen the trail so it wouldn't fall off the mountain when it woke up still drugged. Halfway down he realised it woke up and was staring at him. He chucked it off his shoulders and ran back up the mountain to the helo.
Lying or not, it's a very funny story.
