All manner of scifi/fantasy/nerdness: RPGs, comic books, Firefly, RPGs, Community, Buffy the Vampire Slayer, RPGs, Avengers, Doctor Who, And RPGs. And comic books. And RPGS. Not a "fandom" blog, unless D&D alignments count as a fandom.
My boss plays DnD in the small group we run once a month, he plays a Bard. Today he was part of a bard competition at a festival and so I made him sing a song out loud to win with the other players as backup singers. He sang Evita - Don’t cry for me Argentina but replaced the town name with the fantasy town’s name. It is possibly the best DnD moment ever.
