The couple: U.S. President Barack Obama and his wife, Michelle.
Love lesson: Marriage can be fun, if you do it right.
We know President Obama loves to sing love songs to the First Lady, and recently to the rest of the world, but the president probably had a few sweet sweet nothings whispered into his ear by Michelle before signing into law the Healthy, Hunger-Free Kids Act of 2010 at Harriet Tubman Elementary School in Washington, D.C. on Dec. 13, 2010. Their balance of romance and practical mutual support is the gold standard for happy wedlock. For years, the couple has been hungry for each other's affection and intellectual appetites, and is known for their blissful balance and graceful dances.
