Lisa: Get out, get out!
Bart Simpson: All right, Lisa. But as I'm leaving, I'm going to be doing this...
[windmills his arms]
Bart Simpson: -and if you get hit, it's your own fault.
Lisa: Fine. Then I'm going to start kicking air, like this...
[kicks up her foot]
Lisa: And if a part of you should fill that air, it's your own fault.
