A guy came up to my apartment door today, and he had a clipboard in hand. He was asking about my cable bill--I sniffed out that he was from AT&T. But when he asked about DVR, I judo'd him into how I could build one myself, which led into how I brew beer. So we spent 5 minutes chatting about that, as he expressed eagerness to learn.
So I linked him to howtobrew.com and gave him one of my bottles of homebrew, making sure to instruct him in pouring properly, and sent him on his way
