This absolutely cracked me up, and my wife didn't understand why I found it so funny. It took a moment for me to realize it's because it's the same schtick as one of my favorite passages from any book.
Two stoned people are having a conversation:
VIRGINIA: Are you hungry?
ANDY: No. (Long reflective pause.) Wait a minute. Did you mean am I hungry for food, or am I hungry in the abstract, like hungry for knowledge or adventure?
VIRGINIA: What are you talking about?
ANDY: You asked if I was hungry.
VIRGINIA: Did I?
ANDY: Yes.
VIRGINIA: Well, are you?
ANDY: Am I what?
