This three-second voice clip from The Boondocks is a single level, unemotional line about lying to a white man, spoken without emphasis or anger. It feels dry and knowing, turning a blunt statement into a joke that lands because it sounds so calm. The line comes from Aaron McGruder's animated Adult Swim series, which follows Huey and Riley Freeman and uses satire to comment on Black culture and American politics.
