Oh, now youve done it.
Some of my favourites (although theres many more I could name):
Homer (about bees): Ow! Ooow! They're defending themselves somehow!
Lisa: Hmm. Pablo Neruda said, "Laughter is the language of the soul."
Bart: I am familiar with the works of Pablo Neruda.
Homer: Okay Homer, just get this stuff into the house as quickly and quietly as possible!
Homer: Homer, you're not listening!
Ive been known to use both "Its defending itself somehow" and "You're not listening" when I hurt myself or do something stupid.
And my favourite skepticism related ones:
Homer: Not a bear in sight. The Bear Patrols are working like a charm.
Lisa: That's specious reasoning, dad.
Homer: Thank you, dear.
Lisa: By your logic I could claim that this rock keeps tigers away.
Homer: Oh, how does it work?
Lisa: It doesn't work.
Lisa: It's just a stupid rock.
Lisa: But I don't see any tigers around, do you?
Homer: ... Lisa, Id like to buy your rock.
Lisa: No dad, I-... ... OK!
Crowd: We need a cure! We need a cure!
Dr. Hibbert: Why, the only cure is bed rest. Anything I give you would only be a placebo.
Blonde Woman: Where do we get these placebos?
Man: Maybe there's some in this truck!
[The crowd smash the truck and its crate of killer bees. One man pops a bee in his mouth]
Man: I'm cured! ... I mean, ouch!
