You thought the Joker was disguised as a nurse, but for Halloween, he was an obstetrician! Brittany Selph and her husband Justin went to the hospital in Paris, Tennessee, on Halloween because Brittany was in labor. Her doctor, Paul Locus, was dressed as the Joker and left for a while to hand out Halloween candy. He was still in costume when he returned to the hospital in time to deliver their little girl Oaklyn at 8:20 that evening.
"When [Locus] came in our room the following morning, in normal doctor attire, he said, 'Sorry I couldn't make it in last night, glad to see the delivery went well'," said Justin. "He was a great sport about it all."
I saw this picture yesterday at reddit, and at that time almost everyone said it was staged. So many redditors assumed that childbirth in a hospital is a sterile procedure, with mandatory scrubbing and masks. That's only necessary for surgery.
