PARIS, TENN - A family was able to celebrate both the birth of their new daughter and Halloween this year, thanks to their doctor. 

Dr. Paul Locus, an obstetrician at the Henry County Medical Center in Paris, Tennessee, helped Brittany Selph give birth to her daughter, Oaklyn, while wearing a Joker costume. Dr. Locus wore the Batman villain's signature green wig, purple suit, white face paint and sloppy red lipstick. 

Selph and her husband, Justin, arrived at the hospital at 12:30 p.m. on Halloween and later told ABC News, "We couldn't help but laugh when he walked in the room."

The doctor told the Selphs that it would be a while before Brittany gave birth and that he could change clothes before the birth of their third child. But Brittany told him it would be ok and that it would be a pretty cool story to tell if he returned wearing the infamous Joker costume. 

At around 8:20 p.m. Dr. Locus, as the Joker, gave Justin the scissors to cut his daughter's umbilical cord. The doctor's congratulations card was signed by "The Joker."
