Knock, Knock!

Earlier this week, The Purple Dragon was hiding in our bedroom closet while I was folding laundry. She started knocking on the closet door, which of course turned into 'Knock, Knock' jokes. Here's how they went (The Purple Dragon provided the answers):

Knock, Knock!
Who's There?
Dragon!
Dragon who?
Dragon who is hiding in the closet!

Knock, Knock!
Who's There?
Dragon!
Dragon who?
Dragon who is four years old!

Knock, Knock!
Who's There?
Dragon!
Dragon who?
Dragon who loves you!

and... Dragon who loves The Pink Princess!
and... Dragon who loves Daddy!
and... Dragon who likes to eat peaches!
and... Dragon who wants a lollypop!
and... Dragon who likes to eat bananas!
and... Dragon who likes purple!
and... Dragon who needs to go potty!
and... well you get the idea.

I must say that she has a much better grasp on jokes than The Pink Princess did at her age. I taught The Princess the joke that goes

Knock, Knock!
Who's there?
Lettuce!
Lettuce who?
Lettuce out! (or 'Lettuce in!' as applicable to the situation)

The Princess thought it was fantastic. The problem came when she started to make up her own jokes.

Knock, Knock!
Who's there?
Tree!
Tree who?
Tree out!

Knock, Knock!
Who's there?
Ball!
Ball who?
Ball in!

It drove us all insane for months. Thankfully, she's improved over time, though when I just asked her to tell me a joke she says she doesn't have one.
