JJ: I am a nee-naw man.
Me: Are you a police nee-naw man, a fire nee-naw man, or an ambulance nee-naw man?
JJ: I am a nee-naw man, a nee-naw man like my puzzle.
Ah yes, that clears that up then (the puzzle is 'rescue squad' and has fire engine, ambulance, police car, tow truck, rescue helicopter and a life boat. My bets are on fireman though, as he's pretty obsessed with fireman Sam at the moment)
