In an effort to be uniquely different, I have none.

Wife has none. Nor any of my three adult children. Son in law has a couple from his Army Blackhawk days.
Nothing against them, just not my style. I told my kids when they still lived at home under 18 years old that if they came home with a tattoo they'll wake up to the sound of a side grinder to take it off.
When they're adults do what you want. None have them (yet).
