Happy birthday to former President George H.W. Bush of Houston.

Bush turned 89 today.

In the past, 41st president in recent years has marked his birthday with stunts such as skydiving.

Today, in celebration of the President's birthday, the The George Bush Presidential Library Foundation is asking the public to put on some "exuberant socks," take a photo and post it on library's Facebook and Twitter pages.

"Select birthday sock photos will be chosen and given to President Bush for his 89th birthday," the library says.

Bush has had medical issues and spent nearly two months in a Houston hospital with a bronchitis-related cough before being discharged in January.

A Bush spokesman says the former president will celebrate with his family at their summer home in Kennebunkport, Maine. Bush's wife, Barbara, turned 88 years old last Saturday. Relatives will help the couple mark both birthdays.
