Phineas and Ferb is one of those shows that i absolutely love and in terms of a lot of shows, it honestly has some of the best continuity i've seen in an animated show. I've watched every episode of Phineas and Ferb at least a few times now and something that i've noticed especially in Season 1. Throughout Season 1 there were a couple of times where there'd be a reference to something that happens on the show that hadn't happened yet on the show. During Jerk De Soleli, Candace's song Evil Boys has her describing a couple of the things that Phineas and Ferb have done over the summer however their mom didn't see them. She mentions that she went back in time, built the treehouse robots and she didn't see them. The second time that i watched this episode, i actually started scratching my head and said that these things hadn't happened yet on the show which leads me to believe that they might have aired the first season in the wrong order. I can overlook that fact though because i love this show.Another example i've thought about is Ladies and Gentlemen Meet Max Modem, Candace finds out that LInda was Lindana however in the episode Flop Starz she wears the Lindana outfit and says that she found it in her mom's closet. I guess you could say that maybe it's not a continuity problem but i don't know, that is one of those things that always made me a tiny bit confused when i think about it.
