Victoria's Secret model Marisa Miller blows a kiss during a visit to Wet Republic, the pool area at MGM Grand Resort and Casino in Las Vegas. The date was May 8, 2010 -- the 126th birthday of President Harry Truman. That's presumably what the pool party was for, though the 'Happy birthday, Harry!' signs must be just out of frame. Harry Truman, the 33rd President of the United States, was born in Lamar, Missouri on May 8, 1884.
