Three goats were eating in a field of grass. One goat was little, another one was medium size, and last one was big.

The little goat started crossing the bridge to the next field, when grumpy old troll raised out of water and said:

"I am going to eat you up!"

The little goat said:

"I am too small to be eaten, my brother is much bigger than me. Why don't you wait and eat him up"

The medium goat said: "I am too small to be eaten up, my brother is way bigger than me, why don't you wait and eat him up".

The troll said to the biggest brother goat: "I am going to eat you up!"

The goat said:

"I am too big to be eaten up!"

He crashed into the troll and the troll fell into the river.
