PHILADELPHIA (CBS) — Pillow fights were taking place Saturday all over the world, including in Philadelphia, for International Pillow Fight Day.

About 50 people, many dressed in pajamas and costumes, showed up with pillows at Washington Square Park near 6th and Walnut Streets and started hitting other participants. Raheem Harvey was dressed a Superman.

“I ran and got this yesterday at the costume store,” Harvey said. “Thank God they had my size.”

Harvey was using a brand new pillow as his weapon.

“I didn’t want to bring a pillow that I drooled on,” he said, “so I actually ran and got this today.”

Kevin Eng was dressed in a pink bunny costume.

“It was Halloween costume that I had lying around, so I thought what a better time to pull it out,” Eng said. “Pillow fights are usually pretty good memories. It reminds me of those childhood days.”

But why a pillow fight?

“I think just to really connect with people,” Harvey said. “It’s always good to do something new and meet people from all over Philadelphia that just want to have fun.”

Some of the pillows were collected and donated to the Philadelphia Animal Welfare Society (PAWS).
