A Guys Weekend is usually a nice chance to get away and enjoy some old fashioned erudite conversation, spirited debate, perhaps a couple games of chess over a gin and tonic.
Here Morgan and Kevin engage in a battle of wits known as Shot for Shot. Basically two players punch each other in the arm until somebody gives up. Plus, you have to be punched in the same arm with which you are punching, so even someone with a high pain tolerance can be taken out with a good strike to the medial deltoid.
