No, just ones I have searched for with no luck. I haven't tried to find every clip and episode.
There are some particular episodes/scenes with Bruno I have searched for and not gotten (The Count counting how many times Bruno dumps trash, The Muscle Song, Camp Uglyyucky, Oscar goes "ta da dump"), didn't feel like searching for all those episode numbers. Also a few Biff and Sully scenes I've been wanting to see (the two prepare for a costume party, Biff gets sick).
Interestingly, one or two of the vacant lot episodes had been in fan collections (and guided on the wiki) before the wiki got info on the whole arc, and I don't think those episodes had even been on YouTube.
