This short voice clip features Robert Freeman from The Boondocks saying Thank ya kindly in a warm, gravelly tone, lasting just under four seconds. It feels polite and good-natured, with a dry, grandfatherly charm that makes a simple thank-you land as a joke. The line comes from the animated series The Boondocks.
