Stay at home dad moonlighting as an associate professor of economics. Mostly interested in gun policy and fishing.

This might be a bad take but as a guy with an off the wall tattoo (got while drunk but definitely not anything bad) I could easily see how this could accidentally happen in Europe. Especially in Croatia.
