When it comes to feats of physical strength, there are a good number of famous human beings on this planet whom you should absolutely not challenge. If you're a member of the common folk, i.e. people who don't get paid to work out and stay in peak physical condition at all times, then you probably shouldn't challenge Usain Bolt to a foot race, Michael Phelps to a swim relay, or, apparently Jason Momoa to a game of Slap Hands.

Mild-mannered writer and Game of Thrones showrunner David Benioff found this out the hard way, though one would imagine that common sense should have nipped that particular idea in the bud; copious amounts of beer probably dulled that sense a bit. But at least he got a good story out of the interaction, so good in fact that the folks over at HBO decided to animate the anecdote as part of "HBO Backstories." You can check it out for yourself below.

Watch the somewhat gory and violent animated short here:

D.B. Weiss and David Benioff detail the time David played Jason Momoa in 'The Slap Game.'

Would you challenge Momoa to a game of Slap Hands? Does your insurance cover "squished hands"? Be sure to let us know in the comments!

Hopefully we get to see more of these animated backstories in the weeks to come as Game of Thrones comes to a close. With that in mind, be sure to visit the following links in order to stay up to speed on all things GoT:
