Throwback Video: Mike Tyson teaches Serena Williams how to box

Mike Tyson may have been one of the most intimidating men in the boxing ring, but he also harbors an appreciation for tennis and has met several of the world's top stars.

The former World boxing champion posted a video of himself coaching 23-time Grand Slam champion Serena Williams, as he showed her how to hit a boxing bag.

Williams took several swings at the bag, held in place by Tyson, as she let out her patented grunts with each shot.

"Wouldn’t want to get in the ring with this GOAT @serenawilliams" wrote Tyson.
