Once upon a time, there was a guy named Tom.
He was travelling through the nearby woods when he got lost.
He was getting hungry and happened upon a plant with red fruits on it.
He recognized it as a plant that many people in his village were scared of. They thought that it was poisonous.
He was hungry enough to eat it anyway.
Luckily, he didn't die. In fact, he quite liked the fruit.
He took several fruits from the plant and walked away.
Somehow, he managed to make his way back to the village.
While there, he told his story of the red fruits.
Everyone was glad to know that the fruit was no longer a threat.
Now, years later, whenever someone from that village sees that particular fruit, they say, "Hey! Tom-ate-those!"
