So I have a wild story.
When I was in the 5th grade, our class had a snake handler come and show off a Boa constrictor. He would put it across our shoulders for a few minutes and call the next kid.
I was the last child to be called, he drapes it across my shoulders and proceeds to mack it to my teacher in the hallway.
that thing wrapped around my torso and right leg. It felt like a gigantic indestructible tube. It tightened around my ribs and I instantly couldn't inhale anymore. It somehow threw me off balance by tightening around my right leg, that combination made me fall into a bookshelf and straight to the floor. My teacher and the corny ass snake handler dude ran in and he pulled it off me and so I'm still alive.
I don't know how adult me would have faired, but once them things wrap around you once, it's over.
