A friend texts to another:
"Hey." They reply, "What's up?"
The first friend then replies with a simple answer, "The sky!" But the other friend intervenes and says, "No, it's the ceiling!"
To then the first friend finishes the greeting with, "Unless you're homeless or six feet under."
Listen up, you knucklehead! You are probably breathing through your mouth right now. The joke here is a play on the common greeting "What's up?" One friend gives a literal answer, "the sky," but the other friend corrects him, saying it's the "ceiling." Then the first friend adds a dark twist by saying unless they are homeless or dead, because then it could be something else entirely.
