The true origin of this famous line came from the skit 'Reparations 04' in Dave Chappelle when black people were paid millions of dollars in compensation for historical slavery.
In the skit, a janior was asked by a reporter when she thought he should give up his job as a truck driver, when in actual fact, he bought the truck using the cash he has. He stated that he can afford the truck and a lifetime supply of cigarettes.
