This is something that I plan on getting done. I think it looks freakin' SWEET.
They cut your ear and then sew it together so when it heals you have an elfy ear! I got permission from my work to do it too. I guess this is actually considered a plastic surgery rather than a body mod in the policy books.
You have any info to share on them? I'm having a hell of a time finding someone who can/will do it.
