Good luck with the humorous approach. Be careful with how far you go, not everyone shares the same sense of humor. I've probably offended a few people with mine.
Tag things properly. I use "offcolorhumor" along with "humor" or "funny" to indicate I'm only joking especially if I'm pushing it. Just telling you this stuff because some people read into things and take the literal meanings. You said "dark" and "dry", those are tough ones for some people to "get". If that's your natural talent though, I'm not a bad influence when I say just go for it.
Thanks for the advice!
