Odd in that you've got a tattoo of a logo from a TV programme. A good TV program, yes, but it's like getting a tattoo the LuthorCorp logo from Smallville. I just find it a bit odd is all.
Yeah, I think some people will find it a bit odd. My flatmate and I really bonded over Lost so it's about our connections (he got the Hydra). But it's also undeniably geeky. I don't mind that too much. Better that than an identikit meaningless tribal symbol or band round the arm, I reckon.
I like the fact that it's fairly abstract so people who aren't fans won't know what it is. And long after the show is gone it will remain just a cool looking design.
