A hilarious parody of Green Eggs and Ham. Numbuh 2 sure knows how to annoy the scientists into eating that "I Can't Believe It's Not Booger"! I also love PARTY and HAMSTER, even if those three aren't in my top favourites either.

An all-round great episode, and bonus points for The Upper Crust! And this dialogue:
Band: "We are the Upper Crust."
DCFDTL: "The who?"
Band: "No, the Upper Crust."

Operation England was hilarious, if partly due to American writers trying to make up their own cockney rhyming slang that makes no sense in England ("oh, I get it - Richard and Mary rhymes with library!" haha no, that's not how we pronounce "library" in England). I also loved Spinach for the Monty Python reference, and The Grim Adventures of the KND was great too. And Interviews was way better than I expected it to be.
