I was wondering why a post from a new redditor was so high on the main page when I was reading a different thread and finally grokked the name. Masuka is the other blood splatter analyst in the TV show Dexter that is the crass, perverse, and overall awesome guy (who gets way too little screentime IMHO). Anyway, it's his AMA that hit the main page.
BTW, if you don't watch Dexter, you must start now. Don't start with Season 5 though, go first watch season 4. Actually season 3. Maybe 2. Actually just start with season 1 and work you way up, it's well worth it.
