It's not necessarily what he says but what he does. Everyone who crosses his path in Overbrook Park leaves in a good mood.
Colberth is the crossing guard who blows air kisses to the cars he stops so that students and parents can cross the intersection.
He's been at this post since 2004, spreading joy every morning.
"Letting everybody know that I'm out here. Letting everybody know that their kids are safe and that I'm a friendly guy," said Colberth. "I pretty much know all the cars. They don't know me personally."
And while his charisma and energy are brightening up the days of those he meets, he says it's actually the other way around.
"They make my day because they're smiling and give me kisses back. They blow kisses back at me, so that makes my day," said Colberth.
