I want to get one of those (almost) unpickable Abloy padlocks, custom machined out of solid Tungsten Carbide, and sneak up on a guy with huge guaged out ears like that, and lock it shut through the hole, then run away with the key, never to be seen again...
Have one of those. PL362
Believe it or not, more secure than the padlocks mandated for securing nuclear weapons. And no "almost". I know people that own and have picked the S&G 951C, which costs $1.5k. I've never even heard a rumor of picking an Abloy.
Eh. I'm not as enthusiastic about it as Boris, but I've seen some interesting body mod. Had a friend that was an awesome coder. Made serious coin. She had half of her head shaved, with a very nice crisp tribal tattoo, the other side was purple and reached her waist. New execs would about have an aneurysm. She kept a price sheet on the wall of her office. $10k for removing the visible piercings, $30k for the hair color, $50k for covering the tats, etc. I think the main bosses put up with it as much for messing with the vendors/partners as much as her good work (she was the lead coder/architect). She could be quite merciless in her technical reviews.
If you're into body mods, you WILL be perceived as unacceptably unprofessional unless you're at almost deity level of skill, or work in more informal environments. Standard businesses? Not so much. Part of the price of art, I suppose. Problem is, most folks with highly visible body mods reinforce the unprofessional demeanor and lack of judgment.
