I'm a big believer that most conversations about any one thing can be had by knowing very little about it...as long as you keep to certain particulars that the other person in the conversation (who is much better and knowledgeable than you will ever be) can expand upon.
By doing this very simple thing your life will be filled with people who think you are a marvelous conversationalist when, in reality, you are nothing more than an ignorant tool.
Which is how I've pretty much amassed a group of friends who love and adore me even though I am really a sub-par human being who contributes nothing but the occasional onion dip at parties.
So, here's a short tutorial on The Game of Thrones that should help you out when you are surrounded by fans of the George R.R. Martin fuck-fest, and which will show you how valuable barely adequate knowledge about this fantasy world will make you look to other people.
