Obama does the Dikembe

US President Barack Obama playfully wags his finger at former NBA basketball star Dikembe Mutombo during remarks at the Let Freedom Ring concert in honor of late civil rights leader Martin Luther King Jr at the Kennedy Center in Washington, January 18, 2010. In his playing days, Mutombo would wag his finger at opponents after blocking their shots.
