Rav Shlomo Zalman Auerbach: Piercing Ears In Young Girls
A Rov's daughter wanted to pierce her ears but her father was uncomfortable with the idea.  But he agreed that they would go to Rav Shlomo Zalman Auerbach and do whatever he says.  Rav Shlomo Zalman did not understand the question  and said, "What is the question?  By us we give the boys a Bris Milah and pierce the girls' ears."  (Aleihu Lo Yibol CM 34)
