Any episode with Ferb as the centric character is epic. :3

@PLAP: Excaliferb! isn't one of the episodes that was shown in other countries before the US; that was Doof Dynasty and Tri-Stone Area, though it's pretty obviously why they were delayed. By the time DD and TSA were finished, Excaliferb and Temple of Juatchadoon were still in production. Disney noticed that all four eps had a time shift theme, so they decided to hold back DD & TSA to premiere with the new two. This way, they could promote them collectively as "Time Shift Weekend", get more viewers, and make moneh. It's a marketing thing.
