The clip posted by our sister station ESPN, has been seen millions of times online showing David Green III delivering his two cents with a package. It's proof that rivalry knows no days off.
"As I was driving up to the house, the first thing I see was the Steelers flag, and I was just like, 'No,'" laughed Green. "If I walk up to the house to deliver this package, you're going to hear my mouth."
"I did want to say something else, but I had to keep it professional," he joked.
Green III is a South Philadelphia native, but he moved to Windsor, Connecticut five years ago.
He says he works on Sundays -- game days, and when he saw the Steelers flag he was ready to unleash a verbal smackdown.
He says he routinely delivers first-class banter given that he lives and works in Giants territory.
"There's Giants fans all out here, I see the Giants flag, I say, 'Thank you for Saquon!'"
The homeowner tells Action News he got a good laugh at the exchange.
He applauded Green's professionalism and trash-talking humor as a funny surprise!
