My husband got one or maybe both of his in Baltimore when he was stationed there in the USCG. I tell him(a non drinker) that they are proof that he has been drunk at least twice in his life.
LOL. Odds are, you're right.
These days, though, a reputable tattoo shop won't ink you if you've been drinking.
I got one when my son was born and plan to get one for every child we have.
