Fear does not exist in the Klein-Arnold dojo!

In an exclusive clip, Bill Klein and Dr. Jennifer Arnold have decided it’s time for their son Will, 4, and daughter Zoey, 3, to take up some extracurricular activities.

Will is excited to attend his first karate lesson, instructing his father to “buckle” him up.

“We got Will a Gi, which is his karate uniform,” Klein says. “He had his little white belt on – the beginner belt, and he kept calling it, of course, his seatbelt instead of his belt.”

By the looks of it, Will is already a natural at karate, bringing his sister Zoey, 3, to the ground, but Klein hopes the sport will help his son learn discipline and self-defense moves.

“As much as I don’t ever want him to get into a fight or be bullied, it does happen from time to time, and the last thing I want is for him to not be able to to defend himself,” Klein explains.
