It's a Christmas Miracle:

Phelan Moonsong says he always wears his goat horns unless he's sleeping or bathing, and so it makes sense that he'd want to wear them in his driver's license photo. How else is an officer, TSA employee, or other license checker supposed to recognize him? Plus, the horns serve as his "spiritual antennae" and help him educate others about paganism, according to Moonsong.

He needed to educate the authorities in Maine a little bit before they'd approve the license photo, but they finally did. He got his new license last week. [...]

The clerk also had some questions, like whether the horns were implanted (they aren't), and whether they were a religious symbol (they are). The clerk took the photo, but then said he'd have to get it approved by the Maine Secretary of State's office, and would need to send some documentation of the fact that these are officially required religious symbols.

Previously, previously.
