The Mayor of Slamtown Johnny Mundo and his real life wife Taya Valkyrie climb into their backyard ring, and did their very own version of the "Kiki Challenge." I think this one is much better, and safer than the other ones I've seen, where people are getting out of moving vehicles and getting hurt. Hell, one guy got hit by another car doing it. Be like Johnny and Taya, if you're going to do the challenge, do it so you don't get yourself hurt.
There's also this Kiki Challenge video, which may just be the best one yet. I don't want to spoil it, but the look on the face of the guy with the handcuffs is priceless.
