Lisa the Vegetarian

Homer: Are you saying you're never going to eat any animal again? What about bacon? 
Lisa: No. 
Homer: Ham? 
Lisa: No. 
Homer: Pork chops? 
Lisa: Dad, those all come from the same animal. 
Homer: Heh heh heh. Ooh, yeah, right, Lisa. A wonderful, magical animal.

Lisa: When will all those fools learn that you can be perfectly healthy simply eating vegetables, fruits, grains and cheese.
Apu: Oh, cheese!
Lisa: You don't eat cheese, Apu
Apu: No I don't eat any food that comes from an animal.
Lisa: Ohh, then you must think I'm a monster!Apu: Yes indeed I do think that. But, I learned long ago Lisa to tolerate others rather than forcing my beliefs on them. You know you can influence people without badgering them always.
