Let's make this birthday one to remember.

78 years old (Born on September 24, 1946)

Happy Birthday, Mean Joe Greene! Time to blow out those candles with the same intensity you used to flatten quarterbacks. Just remember: your cake is safer than an opposing offense—no one dares touch it when you're protecting the line!

Four Super Bowl rings aren't just decorations—they’re reminders that nobody dominated quite like number 75 in Pittsburgh black and gold. From crushing tackles to intimidating presence on-field for all of your stellar thirteen seasons with the Steelers, we've seen nothing but greatness.

So here's wishing you a day filled with laughter (and easy-going refs!). Cheers to another championship-worthy year ahead!
