March Madness is a time for numbers. The number one, for instance, represents the top-seeded Kentucky Wildcats or, perhaps, the number of eyebrows that their star freshman forward, Anthony Davis, has.
You know you're good when you not only rock a unibrow with abandon, but your mom shows up to a game with a unibrow mask. Simply put, dude's a beast. If you want some more stunning numbers from the 6-foot-10 Davis, he averaged more than 14 points, 10 rebounds and almost five blocks per game during the season.
One more number: He celebrated a birthday Sunday. His 19th.
But the tournament is much bigger than one player, and there are several teams - especially in the loaded South region - that will be looking to take John Calipari's Wildcats down a notch.
The games tip off today at 12:15 p.m. ET. Here's a look at the tournament by the numbers, with big ups to Amy Roberts at the CNN Library for putting these together:
67 – Number of games in the 2012 NCAA Men's Basketball Tournament.
68 – Number of teams invited to be in the tournament.
1 in 4,294,967,296 – Chances of creating the perfect bracket through the first round.
CNN examines statements made by Republican presidential candidates during Wednesday night's CNN/Republican Party of Arizona debate in Mesa, Arizona.
Newt Gingrich criticized the chairman of the Joint Chiefs of Staff for characterizing Iran as a "rational actor" in international affairs and defending the possibility of preventing an Israeli attack on Iranian nuclear sites
The statement: "The fact is this is a dictator, Ahmadinejad, who has said he doesn't believe the Holocaust existed. This is a dictator who said he wants to eliminate Israel from the face of the Earth. This is a dictator who said he wants to drive the United States out of the Middle East. I'm inclined to believe dictators ... If you think a madman is about to have nuclear weapons, and you think that madman is going to use those nuclear weapons, then you have an absolute moral obligation to defend the lives of your people by eliminating the capacity to get nuclear weapons."

CNN examines statements by Republican presidential candidates during Thursday night's CNN/Republican Party of Florida debate in Jacksonville, Florida.
Mitt Romney and Newt Gingrich both accused each other of having financial interests in Fannie Mae and Freddie Mac
The statements: "We discovered, to our shock, Gov. Romney owns shares of both Fannie Mae and Freddie Mac. Governor Romney made $1 million off of selling some of that. Governor Romney has an investment in Goldman Sachs, which is, today, foreclosing on Floridians." - Gingrich
"First of all, my investments are not made by me. My investments, for the last 10 years, have been in a blind trust, managed by a trustee. Secondly, the investments that they have made, we learned about this as we made our financial disclosure, have been in mutual funds and bonds. I don't own stock in either Fannie Mae or Freddie Mac. There are bonds that the investor has held through mutual funds. And, Mr. Speaker, I know that sounds like an enormous revelation, but have you checked your own investments? You also have investments through mutual funds that also invest in Fannie Mae and Freddie Mac." - Romney FULL POST
Sen. Mellencamp? The title certainly strikes a chord with more than 7,708 members of a Facebook group that's trying to convince rocker and Indiana native John "Cougar" Mellencamp to run for the U.S. Senate to fill the seat that Democratic Sen. Evan Bayh soon will leave behind. The 58-year-old singer, known for his rock songs about the heartland and the working man, was an inaugural organizer of the Farm Aid concert benefit for family farms in 1985.
A vocal critic of George W. Bush's administration and the Iraq war, Mellencamp participated in the 2004 "Vote for Change" tour. In 2008, Mellencamp requested that GOP presidential hopeful Sen. John McCain stop using his songs at his campaign rallies. Mellencamp also recorded a radio ad in support of Barack Obama that aired in Indiana in the lead up to the November 2008 vote. In February, the Rock and Roll Hall of Fame member performed in a concert at the White House featuring civil rights music. In light of the fans' recent push to see him in office, the CNN Fact Check Desk wondered how many other entertainers have made the jump successfully to politics.
Fact check: What other entertainers have become lawmakers?
During debate Tuesday on the Senate floor, Minority Leader Mitch McConnell, R-Kentucky, expressed concerns about the cost of the health care bill.
"The bill that the White House and its allies in Congress want to vote for would actually drive costs up," he said. "Overall health care spending would go up by more than $200 billion under [this] bill."
