The Big Fib S01E20 - Math & Faces

Yvette welcomes 10-year-old Pepper to the Silly Warm-up Round featuring two experts on Math. Alex is a Mathematician, who describes where you can find the Fibonacci sequence throughout nature. Linus, "The Minus," is a world champion Mathlete who shows how she literally "crunches" the numbers! CLIVE tells his first 
and only lie. Anne and Sirena are two adults, who claim to be experts on Faces. Anne is an Anatomy Professor, and she explains how many mammals, not just humans, smile. Sirena is a Forensic Psychologist, who discusses how your pupils are a big giveaway on whether or not you're lying! Pepper knows quite a bit about 
Faces, but can she find the fibber?
