This morning J (5) was playing "Three Little Pigs" with L (7) and S (3).  They'd prop up pillows or blankets or some other structure, and then he'd come along as the wolf and they'd act it out.

Dh overheard this:

J: Little pig, little pig, let me in!

one of the girls: Not by the hair of my chinny chin chin!

J: Then I'll huff, and I'll puff, and I'll blow your house down!  FFFFFFFFFFFFFFFFFFFFFFFF (blowing sound)

Pause.

J: Didn't work.
