Cuz I'm a Blonde

Alana was walking around singing the refrain from "Cuz I'm a blonde--yeah YEAAHH yeah". Finally we asked her to stop, because it was getting really old. Keith said "You're really more of a brunette, not a blonde." Then we asked if any of the kids in her class were blonde. "Isn't Isabelle blonde?" "No." "I thought she has yellow hair." "She does, but she's not blonde." "Uh, yes she is. Blonde means you have yellow hair." She pondered. "I thought blonde was when your eyes don't work."
