Raising Don Rickles

My five year old is a piece of work lately.  Just had this conversation:

(Me on the back porch, him in the back yard)

Me:  "What do you want for lunch?"

Him:  "Nothing yet!" (This is the third time I've gotten this answer)

Me:  "It's almost 2 o'clock, you need to eat something."

Him:  (Pointing a stick at me) "Don't rush me lady!"
