Phineas and Ferb (2007)

I Scream, You Scream - S1-E15

Continuity mistake: In the scene where Doofensmirtz talks about how the sign blocks his view of other people's pain and misery, his window faces the sign. Then in the next shot where the laser blasts the sign, the Doofensmirtz evil inc. logo is facing the brick sign and the windows are facing the other way.

Candace: Mom! Phineas and Ferb are making a title sequence.

The Fast and The Phineas - S1-E4

Trivia: Jeremy mentioned that one of the cars' name was Billy Ray, making a reference to Hannah Montana , which country singer Billy Ray Cyrus stars in Mitchell Musso who played the voice of Jeremy also stars in Hannah Montana.

Show generally

Question: Based on Wikipedia, the show had 222 segments altogether including 2 films, and a Christmas special, meaning the show featured 2 different summer vacations (one before the Christmas special and one after). If Phineas and Ferb only have 104 days of summer vacation per-vacation, shouldn't there be no more than 208 segments and films put together (1 day per-segment/film) or not? Also, if there really were 3 different vacations, how come the characters don't look to have grown at least a little in height throughout the years (the facial looks are reasonable though because they still look exactly the same when it shows some of them older in the episode "Last Day of Summer," if I remember correctly).
