Three little pigs

When we were walking to school on Wednesday, Stuart says, "Can we be three little pigs?"
OK.
"I'm the woof."
I'm the pig with the sticks.
Benjamin was an airplane at that point, but he was listening.
Stuart said, "Little pig, little pig, let me come IN!"
I said, not by the hair of my chiny-chin-chin.
Stuart said, "Then I'll huff, and I'll puff and I'll blow your house down," and spit on my hip.
Benjamin said, "Do it to me!"
Stuart said "Which pig are you?"
Benjamin said he was the pig with the straw.
Stuart said "OK."
"Go, Stu!" Benjamin prompted.
Stuart said, "Knock knock."
