Some doors, like the front gate of the White House, are tough to walk through. The White House has one phalanx of security after another, and you simply don't get in unless you are wanted, unless you have clearance, unless you have an appointment.

Some people do get into the White House based on who they are. Some get in based on who they know.

On Sunday July 26, 2009, one of the biggest and most famous men in the world—NBA star Shaquille O'Neil—tried to get into the White House without an appointment. At 7-1 and 325 pounds, with a winning smile, and NBA championship rings on his fingers from years of playing for the Los Angeles Lakers, Shaq has what it takes to walk into most places he wants to go. Doors open for Shaq.

And so, Shaq decided to put his celebrity, and President Obama's love of basketball, to the test. He was on a D.C. sports radio show on Friday July 24th, and he put this question to the listeners: "Check this out, I got on a nice suit, I'm in D.C. paying a visit, I jump out of a cab in front of the White House, I don't use none of my political or law enforcement connections. If I go to the gate and say, 'Hey, I'm in town, I would like to see the President,' do I get in, or do I not get in?"

Two days later, Shaq gave it a try, and just as Shaq has rejected those who would drive past him to the hoop, so the security guards at the White House gate rejected him.

Later that day, Shaq tweeted, "The White House wouldn't let me in, whyyyyyyyyyyyyyyyy."
