just wanted to drop by and say that this very episode was imo the best yet.
i laughed, I smiled and grinned and the puzzles itself were brilliantly paced and arranged. so many moments of utter genius, agent superball was hillarious (no cameras please, i need a moment), the inclusion of old characters and hints to other episodes a highlight. an episode like this can only come and be written after you already had a bunch of classic ones, i was reminded of Futurama and the universe they created for themselves, I think you reached that quality with this one. and the last scene after the credits - had me jumping out of my seat.
...it's pure comedy in interactive cartoon motion....
