Allison Williams is apologizing for her past behavior in the 4th grade, where she would kick boys "in the balls" with her wooden clogs. The actress recalled the story while appearing on the June 24 episode of The Kelly Clarkson Show.

Williams, 37, told host Kelly Clarkson that she found it "amusing" and "fascinating" to see how the boys reacted when she kicked them with her wooden clogs. She explained that the boys would completely change their demeanor, becoming nauseous and crying.

Williams issued an apology to her former classmates, saying, "To all the boys I went to school with, I am so sorry. I hope it caused no permanent damage."

The Girls alum also warned anyone thinking of recreating her wooden clog experiment with her 3-year-old son, Arlo, saying, "And to all the future people in Arlo's life, if any of you kick him in the balls, I'm coming for you."
