Don, MacArthur and others in “Brazilian Pain Forest”

In this All-In challenge, one team member has to make a headpiece, the other a tail, worthy of walking the parade during Carnival. When this local approves of their handy work, they'll get their next tip.

Piece of cake. [interview] I know how to make costumes. I went trick-or-treating as a beat cop for 10 years straight.

[to her daughter while grabbing onto a vine] Hop on, and hold on! DO IT!

Mom, stop. You know screaming makes your neck waddle.
