The only thing bear is afraid of, as far as I've ever seen, is stuffed animals.
He's been in bar fights, talked to attractive women, snorted a line of something white and powdery off a homeless man's ass crack.
I thought he was immortal.
Then, on the day after Christmas, this year, I swear, my daughter showed him something she got from "Build-A-Bear" (stuffed animal).
He pissed himself.
Then grabbed my wife's tits and hopped in the back of his jeep in the fetal position crying and sucking his thumb.
Go Cast Iron!!!
