The Dallas Cowboys are one of the most popular franchises in American sports. Forbes values them at $10.1 billion, and plenty of that has to do with their plethora of fans. They have the backing of multiple celebrities, although no one has gone as far as Shaquille O'Neal while showing their support for the franchise.In an August 5 edition of "The Big Podcast," the four-time NBA champion said he was sure about the Cowboys beating the defending Super Bowl champion Philadelphia Eagles in Week 1.“We winning this year. I’m guaranteeing it,” O’Neal said. “If the Cowboys don’t win this year, I’ll wear that Charles Barkley dress on the strip of Las Vegas.“I will wear that dress right there in front of my restaurant at the Paris Hotel in Vegas. I’m a man of my word. If we lose to the Eagles I will wear this dress in front of my restaurant at the Paris Hotel.”Fast forward a week, and he doubled down on that wager, going as far as to say that he would walk a full block naked if Dallas didn't go all the way this season."We got a shot every year. We're going to win the Super Bowl, and if not, I'll walk a New York City block, butt *ss naked," he said.The Cowboys aren't among the favorites to hoist the Vince Lombardi trophy this season.

When asked why he roots for the Cowboys, the legendary big man revealed that he used to tell people that he was one of Ed "Too Tall" Jones' sons.“When I was young, I used to tell people ‘Too Tall’ Jones was my father,” Shaq said. “That’s why I like the Cowboys. And I don’t ever switch up. I’m not one of these guys that, you know, whatever team is hot you switch up.”'Too Tall' was one of the most dominant defensive ends of his generation. At 6-foot-9, he was considered a little too big for the position, so it's easy to understand why Shaq liked his game.
