I think it was to Arnold......:)

After all, instead of Mr. Drummond, Dana said the line, too. I think it was the third season.

it was called roots:talk:

OMG! I remember that! :lol:

I remember that too, the look she had on her face.

Is the "Roots" episode the one where Willis and Arnold buy percussion and want everything to be black ?

Well truth fully everybody in the family said it once
Willis finally said in episode Drummond's Korean lover that was in mid season 4

that episode was good.
