I live near Atlantic City, so I know a lot of people who work in the casino industry. They all have hilarious stories about celebrities and their out-on-the-town exploits, usually they involve some B-list celeb doing something dumb in a drunken stupor. These stories can be funny or interesting, but they're never anything groundbreaking.

Things always step up when you hit America's real gaming mecca, though. Rich Strafella, a VP and long-time gaming exec at the Hard Rock Hotel in Las Vegas, was recently asked by UrbanDaddy.com to share his favorite celebrity story.

"I remember a night when Wayne Gretzky insulted Michael Jordan at the table. It was a private salon game. Michael had ordered a drink from the cocktail waitress, and he gave her a five-dollar chip. Wayne took it off the cocktail waitress's tray, gave it back to Michael, grabbed a hundred-dollar chip from Michael's stack and put it on the cocktail waitress's tray. Then he said, "That's how we tip in Las Vegas, Michael."
