It's a popular concept in Asian hospitals, particularly in East and Southeast Asia. They have a staple gold earring with colored jewel center for the baby (you can choose the colors for the jewel) that they'll add on your hospital bill.

This earring. I can't find anything clearer so...

I'm glad the bro has BroCon and not romantic BroCon. I didn't know you could get your ear pierced in the hospital...
