Can you guess?

Levi is so funny. He and Jace were playing downstairs yesterday and he ended up getting mad at Jace. All of a sudden Pete heard him say to Jace, "you're just an empty-headed female!" Pete came and told me about it and we laughed. Now, before you go thinking that's the kind of name callin' that goes on around here (ha-ha) I want to let you know that line is from a movie. Do you know it?
