8. 'Big Girls Are Best'
Bono and his wife Ali Hewson had two little boys right around the time of U2's big comeback album All That You Can't Leave Behind. Pregnancy and childbirth were clearly on Bono's mind when he wrote the lyrics to "Big Girls Are Best," which came out as a B-side to "Walk On." "She's got the baby at her breast," Bono sings. "She knows big girls are best."
