 Yeah, it's almost like this little secret handshake. You know, I've heard it in songs. I'm thinking there's a Huey Lewis song with Pittsburgh PA in it and James Brown. Didn't James Brown sing Pittsburgh PA in Living in America as well? Yeah, that's right. So it's been around for a while, but I don't think we have a good explanation of why people say that. It's the same reason people do anything more than once and pass it on to person to person, right? Yeah, maybe a point of pride.
