A little girl was helping her mother prepare a fish for dinner. She laid the fish carefully into the baking pan.
“No, no,” her mother said removing the fish from the pan “We have to cut off the head and tail first.”
She duly chopped them off before replacing the fish back into the dish.
The little girl thought for a moment then turned to her mother asking,
“Why do we do it like that mammy,”
Her mother thought for a while and then said, "I've always done it that way - that's how babicka (Czech for grandma) did it."
Not satisfied with the answer, the little girl went to visit her grandma to find out why she cut the head and tail off the fish before baking it.
Grandma thought for a while and replied, "I don't know. My mother always did it that way."
So the little girl and the grandma went to visit great grandma to find ask if she knew the answer.
Great grandma thought for a while and said, “Because my baking pan was too small to fit in the whole fish”.
