XD I remember that episode. It was back before Lila and when he was infatuated with Ruth. My friend and I recently watched the Valentines day episode where Ruth turned out to be extremely shallow, and Helga pretended to be Arnold's pen pal. I think Helga was the best character. I remember the one with her sister Olga. Especially the one where Olga got a B and when she saved her from marrying a douche.

The What's Opera, Arnold one reminds me of my favorite bugs bunny video. "Whats Opera doc?"
I believe ( not the one where they sing in the barber shop but the one where Elmer sings Kill the wrabbit)
