Out of order?
Is the show done out of order? Because of Netflix, it's all over the place. I got my wife the complete series and like for example, the Christmas episode, it says on Wikipedia that that episode is Season 3, Episode 25. But in the DVD complete series, it's Season 4. Also, I could swear Kelly and Jessie left earlier on, yet they appear for the senior prom and graduation.
How does any of this make sense, you know? Is it out of order?
