don watcher: i'm don watcher. i'm known as the bear man. i'm a chicago bears die hard fan. bear down. [music playing] bear misterio: so bear misterio was born-- one day, i was walking, and i saw this lady selling luchador masks. and when i saw this blue and orange, it was just calling my name. after that, i just added the mohawk, my signature, and i became bear misterio. [music playing] not many people know my true identity. i have a three-year-old son. he knows my identity. i have a mask for everything. i have a mask for the shower. whoa, whoa! what's going on here? i run the chicago marathon every year, so i have a mask for that as well. a lot of my tailgating crew, first and ten, some of them do because i stay with them every time we travel to a game. but the majority, nobody knows. [music playing] don watcher: the bear is the greatest predator in north america, and i kind of wanted to portray that. so in 96, i went to a taxidermy shop, and i bought a black bear head rug. i cut the head off the rug. i made it fit on my head, and over 25 years later, i'm still bear man.
