I went into rewatcing CCS looking for highlight episodes to tell a friend of mine to watch (she's read the manga, but not seen the anime). The ones that I remembered from way back when were indeed the standout episodes, but all the filler eps I groaned at going into (Sakura's adventure with the Little card, for instance) ended up far exceeding my expectations. A lot of them are more lolzy than I remember, too. I was really pleased. Bravo Madhouse.

You have a point there with Eriol. :) I'll just have to keep telling myself that it was CLAMP themselves who put Rika and Terada-sensei together. A 9 year age difference is nothing to theirs!
