Grohl reflects that after spending the past several years taking his daughters on tour with him have turned them into bonafide globetrotters, comfortable with the frequent changes and traveling. He shares an anecdote from a trip to London, when he decided to take Violet and Harper to Harrods’ toy department and gave them each one hour to find a toy that would fit in their suitcases. Grohl watched with fatherly joy as his daughters frantically ran around the store, eventually narrowing their search down to Barbies. When time ran out and neither girl had chosen one, Grohl picked up a random Barbie and joked that it was for him. When he looked at it, he realized that he had unknowingly picked up a Joan Jett Barbie, and he ended up buying it for himself. The girls each picked out their own doll, and the three of them headed for the hotel.

At the hotel, the girls asked if they could play with Grohl’s Joan Jett Barbie. Grohl realized they do not know who the real Joan Jett was, and he explained that she was “a feminist icon who proved to the world that women can rock even harder than men” (326).
