MATT WRIGHT: Brooke just caught a rattlesnake.
BROOKE: Thought I'd do a little snake wrangling to get
prepared for 21 days in Africa.
Naked.
Not afraid.
And--
Maybe a little afraid.
My husband, Matt Wright, has been on "Naked and Afraid"
twice.

I'm tired of looking at his satchel and, frankly,
smelling it.
I would love the opportunity to get out there and have my own.
Yee-haw.
Woo.
My name's Dylan McWilliams.
I'm from Grand Junction, Colorado.
I'm 20 years old.
Most people know me as the guy who was bit by a bear,
a shark, and a rattlesnake.
REPORTER: He woke up with his head in a bear's mouth.
A bear had a hold of my head and was dragging me.
The bear let off because I was punching him in the face
and poking his eyes.
I don't think he liked that too much.
REPORTER: A surf vacation for Dylan
McWilliams suddenly turned into a life-or-death struggle.
Something hit my leg pretty hard,
and I saw a shark underneath me.
REPORTER: McWilliams says a six-foot tiger
shark bit his leg.
DYLAN MCWILLIAMS: The shark kind of just grabbed like that.
REPORTER: Three years ago, Dylan McWilliams was
also bitten by a rattlesnake.
The odds of that happening to one person
is 893 quadrillion to one.
Surviving in Africa where there's lions
and crocodiles and leopards--
what am I thinking?
Why am I doing this?
It's mind-blowing.
I'm coming, Africa.
