Pizza Toppings

The theme of our classroom is Pizza right now and at circle time we were singing a song about toppings.
It went like this:

"Pizza is yummy.
We like it a lot.
Someone likes _____ best
On the top!"

The teacher started changing out the blank space with pepperonis, sausage, mushrooms, and cheese.

Then all the sudden, in dead silence, a girl called out,

"I like cheese on my top!"

It made me and the other teachers giggle.
