how about this one:
you ask someone the question:
what is happening?
he/she responds: I don't know
you: You don't know what is happening. That is exactly what is happening. What is happening is that you don't know what is happening.
he/she: you know what is happening but you don't know that you don't know. what you know is that you think you know but you don't really know either because i know i don't know.
you: I know that i know because i can tell that you don't. what you know is that you think i don't know but i do. you still don't know but i do.
he/she: if you know that i don't and you do, then what makes you think you know about you knowing if your knowlage is based on mine not knowing?
you: i know i know because i know you don't know you that don't know. to know that i use the Stravinsky algorithm.
he/she: I know the Stravinsky algorithm. But you didn't know. i win
you: not really look:
OK i got tired
