There's a really good series by pen and teller called "Bullshit" the title of the show pretty much gives you the idea what they think about bigfoot and the paranormal.
Are you ready for the fire? We are firemen. WE ARE FIREMEN! The heat doesn’t bother us. We live in the heat. We train in the heat. It tells us that we’re ready, we’re at home, we’re where we’re supposed to be. Flames don’t intimidate us. What do we do? We control the flame. We control them. We move the flames where we want to. And then we extinguish them.
Impersonation is treason.
