First Joke

Sera's been working on this joke thing for some time now.  She didn't quite get it.  She kept doing a variation of a knock knock joke, but without a punch line.  Her typical version went like this:

Knock, knock

Who's There?

Strawberry

Strawberry who?

::peals of laughter::

This week she told what I consider her first real joke.  I think she learned it in school.  She told me that daddy taught her, but he denies it.

Why did the chicken sit on the eggs?

I don't know.  Why?

Because they didn't have any chairs!
