Naming the Daughters

A man has three daughters.

The first comes up to him and asks, "Daddy, why was I named Rose?" He replies, "Because when you were born, a rose petal fell on your head." The second daughter asks, "Daddy, why was I named Daisy?" He replies, "Because when you were born, a daisy petal fell on your head." The third daughter yells, "Hnnnngggghhh!" The dad replies, "Shut up, Cinderblock!"
