Walter: So, what's distracting you from setting the table?
Kat: I'm turning my giant carbon footprint into a cute little baby foot - by converting my car into a biodiesel.
Walter: Huh, by yourself?
Kat: You think a woman can't do it?
Walter: Sure she can if she's a mechanic. You do realize that this is your only car and if you destroy it I'm not getting you another one.
Kat: Relax Dad, I printed a comprehensive instruction manual off the internet. It got nine out of ten stars.
