Raise your arm and slap palms with a stranger: Today is National High Five Day.
The holiday, which originated seven years ago at the University of Virginia, annually falls on the third Thursday of April. Want to celebrate? You just have to exchange a bunch of high fives.
The official Web site for National High Five Day includes a high five documentary, as well as a list of songs included on the National High Five Day Soundtrack. Selections range from "Honky Tonk Woman" to "Proud Mary."
