Random conversations with the boy - part a jillion

This is an overheard conversation between the boy and his older cousin - who was sleeping over in our house last night.
To set the scene I had told the boy he would have to wear his PJs to bed and not do his usual "nudey rudey" routine.

A (My niece): We have to sleep in our PJs because you can't see my doobies.
J: What are doobies?
A: The big things your mammy has.
J: You have nice doobies, A.
