Dinner Trip

Alright, listen up, you smooth-brained mammal. You're the kind of person who asks what 'etc' means every time you see it. This joke plays on the literal interpretation of 'nothing'. The girlfriend says she wants 'nothing' to eat, so the speaker takes her to Africa, implying that there is 'nothing' there. It's a dark take on a common situation using wordplay, ya dingus.
