It was dinner in the plane, and the flight attendant asked the passenger if he would like dinner.
"What are my choices?" the passenger said.
"Yes or no," the flight attendant replied.
Dinner Choices on a Plane
Explanation
The humor comes from the flight attendant's response, which plays on the literal interpretation of 'choices' in the context of a meal. Instead of listing menu options, she offers a binary choice of accepting or declining food altogether. It's a play on expectations and a bit absurd, as passengers expect menu options, not a yes/no decision on dinner.
