Archie wants to do whatever Carter does, and Carter tells a mean knock knock joke. Yesterday Archie took a turn at the wheel:
Archie: knock knock.
Me: Who’s there?
Archie: Nipple.
Me: Nipple?
Archie: Nipple.
Me: (Making a mental note to follow up on the speech therapist) Nipple?
Archie: Nipple.
Me: (giving up) Nipple who?
Archie: Nipple you don’t have a car do you? (room is full of baffled silence) do you get it?
Me and Carter in unison: No.
Archie: (puzzled) What, are they supposed to rhyme or something?
