Clever Cow Puns

My daughter will be 4 in December and I've been teaching her jokes involving animals and the sounds they make. I had taught her;

What do ducks eat? Quackers

What's a cows favourite place to go? To the mooovies.

She thought they were hilarious and for the next few days I would ask her to tell me a joke and she would repeat one of these jokes and we would laugh together. I asked her this morning to tell me a joke expecting one of these same jokes that she knows, then she took me by surprise by asking;

Why was the sheep on the naughty step?

I was taken aback and wondered where it was going, so I replied;

I don't know. Why was the sheep on the naughty step?

Coz he was a baaaad boy.

Few moments of stunned silence then me and the wife looked at eachother, then burst into fits of laughter while my daughter beamed with pride. Her twin brother is often on the naughty step for being a 'bad boy' and I'm thinking that she has put 2 and 2 together and came up with infant/toddler comedy gold. Very clever, and very proud dad.
