A mother was sitting on the couch reading a book when one of her children walked up to her and said, "Mummy, why is my name Petal?"

The mother replied, "Because when you were born, a petal fell on your head."

The next baby walked up and asked, "Mummy why is my name Rose?" she replied,

"Because when you were born, a rose fell on your head."

The last baby walked up to her and said, "BLAS CLAFLAS YIFRASSAM TASSM POONNFFFIINRTY."

The mother replied, "Please be quiet, Refrigerator."

"BLAS CLAFLAS YIFRASSAM TASSM POONNFFFIINRTY."
What is the point of this sentence？
