This joke centers around a conversation between a nephew and his uncle, where the nephew keeps asking the uncle how he’s doing, but the uncle only responds with a vague "hmmm." When the nephew suggests something might be stuck in his throat, the uncle still replies with "hmmm." The twist comes when the nephew startles the uncle by saying his wife is coming, and then points out that the uncle's teeth have fallen out. The punchline unfolds when the uncle explains the cause of his lost teeth in a funny and unexpected way, hinting at an incident with his wife. The humor comes from the surprising twist and the uncle's sarcastic tone.
