Black Parents and Elevators

Listen up, buttercup! This joke is playing on two meanings of "raise" and "belt," see? You probably thought "raise" only meant to lift something, didn't you, you big dummy? But "raise" also means to bring up a child! And a "belt" in an elevator is a part that helps it go up. But a "belt" for a parent, especially in this stereotype, is used for... well, for spanking a kid to "raise" them right. Get it? You probably need a diagram, you dimwit.
