Arthur, Season 8 (2003)

Mrs. Read:
Dora Winifred Read, what did you just say to me?!

D.W.:
Uh... Can I have a soda? Tibbles!

Mrs. Read:
What are you doing?!

D.W.:
I'll get it! Uh, Arthur did it?

Mrs. Read:
Well, D.W., you're off the hook this time, because you didn't know what you were saying. But I hope you know now that swear words are not appropriate, especially for 5-year-old children.

D.W.:
Why?

Mrs. Read:
Because most people are offended by them. It's as simple as that.

D.W.:
But why? What do they mean?

Mrs. Read:
I guess you could say they mean "I want to hurt your feelings". Good night, D.W.

D.W.:
Now, why didn't somebody tell me that in the first place?
