Danger Everywhere

Recently my class and I were put out into the field for a training course. Before the course began we were given a safety brief.
Instructor:

"Alright class, here's the down low, everything out here will kill you or injure you. First, there are rattle snakes out here, if you hear them, merely go around them at a safe distance. Next, there is a cougar, she has two cubs. If you see her, don't run, don't turn around. Just maintain contact, and very slowly back away and she shouldn't bother you. Last class saw two brown bears out here. They are in the course area. If you see them, act bigger then you are and that should scare them off, if you find yourself being batted around, play dead, if they start eating you, fight for your life... Coyotes are your next concern, the four legged kind aren't going to bother you but you will hear the two legged kind on your radios. Don't go into the mountains, it's one of their favorite crossing areas. OH! and the trees, that kind over there, there, and there? Those have barbs which can stick up to an inch into your skin which we'll have to cut out. Also, watch where you lay down, the ants and scorpions are not your friends. Long story short, just about everything out here can kill you."

Student:

"Good grief, is there anything else? Chupacabras perhaps?"
