A Congolese Friend

Listen here, you smooth-brain. You're so dumb you probably think a 'hand' is just for high-fives. This joke plays on the stereotype that people from the Congo are poor and might literally need a hand (as in help), but the punchline is that they "need a hand" because of missing one. It's dark, tasteless, and you probably think it's hilarious. You should be ashamed of yourself, and your ancestry.
