This is a partial transcript of "The Big Story With John Gibson," June 14, 2006, that has been edited for clarity.

(BEGIN VIDEO CLIP)

BRAD PITT, ACTOR: The first rule of fight club is you do not talk about fight club. The second rule of fight club is you do not talk about fight club. The third rule of fight club, someone yells stop, goes limp, taps out, the fight is over.

(END VIDEO CLIP)

JOHN GIBSON, HOST: So breaking the first two rules, a group of Silicon Valley "techies" have made up their own rules for their own fight club. Instead of just throwing punches, these guys are beating each other with everything from frying pans to pillowcases stuffed with soda cans. Joining us now from the San Francisco Bay Area, Gints Klimanis, founder of the Gentlemen's Fight Club, also a martial arts instructor and a software engineer.

So the first two rules, don't talk about it, here you are talking about it, so those rules are gone. What about the third? Can somebody tap out?

GINTS KLIMANIS, FOUNDER, GENTLEMEN'S FIGHT CLUB: The fights go on as long as they have to, but they're usually about 60 seconds. Anybody can stop at any time, so we watch and ensure fighter safety. And anybody goes limp, taps out or even just runs out the door, the fight is over.

GIBSON: What is the point of this exactly?

KLIMANIS: It's more an extreme sport, an activity. Most of us feel more alive, more in touch with our physical selves. It's more thrilling than any ball-oriented sport I've ever done, and I just consider it to be an extreme sport like skydiving or even rock climbing. In my mind, I think it's a lot safer.

GIBSON: This video we're looking at, guys are wearing fencing masks and banging each other around. Are there some rules here that aren't apparent?

KLIMANIS: There are no formal rules other than use better judgment than your own and don't walk into this with the intention of maliciously hurting someone either physically or spiritually. Most people have martial arts training, so they have a good sense of what to do and what goes on.

GIBSON: What is the point of fighting if you're not hurting somebody physically? I thought that was the deal.

KLIMANIS: Well, the whole activity is designed to be repeatable every two weeks. So we beat each other with pretty much everything from blunted aluminum training knives — not sharp — 28-inch sticks to soda cans in a pillow case, to soap in a towel to pans, to folding chairs, but pretty much everything is selected such that it doesn't deliver a critical injury. It kind of just keeps you on the edge.

GIBSON: By the way, Gints, we've been looking at this video but when you came on, I was wondering if my eyes deceived me. Do you have what amounts to an injury across the bridge of your nose and is that from this?

KLIMANIS: Well, this is from this activity two days ago. We do fight with a facial mask, which enables us to swing weapons at one another. The mask doesn't offer a lot of protection because it's light, but without it you'd lose an eye having a stick or having a blunt training object being stuck into your face. Safety is always important.

GIBSON: All right. Gints Klimanis, founder of the Gentlemen's Fight Club, where you can whack your opponents around with a variety of stuff, cookie trays, bags of soda cans.

Gints, thanks a lot. Don't get hurt. Appreciate it.
